The audio-frequency information of view room 2 will be transmitted by the bridged appearances of above-mentioned foundation, and respectively at the end IPPBX1 and the end IPPBX2
The stereo process of meeting room voice after being bridged, to realize the voice sharing of all participant phones.
Fig. 3 is the flow chart that the meeting room bridge joint of the specific embodiment of the invention is realized.It can be seen that realization of the invention
The following steps are included:
Step S310: it sends meeting room bridge joint and requests, where the IPPBX1 to opposite end meeting room 2 where local meeting room 1
IPPBX2 send the bridge joint request of meeting room, and wait request response code.
Step S320: receiving meeting room bridge joint request, and the IPPBX2 where opposite end meeting room 2 receives meeting room bridge joint request
Afterwards, and " OK " response code is sent.
Step S330: bridged appearances and meeting room stereo process are established, after IPPBX1 receives " OK " response code, with server
IPPBX2 establishes bridged appearances, while starting the stereo process of local meeting room 1, the local meeting room 1 of generation at the end IPPBX1
Audio-frequency information.Stereo process herein is that the audio for inputting all participant side's routes 1 of meeting room 1, route 2, route 3 carries out
Mix superposition processing.
Step S340: carrying out the communication transfer of meeting room audio-frequency information by bridged appearances, i.e. IPPBX1 is by above-mentioned local
1 audio-frequency information of meeting room is sent to IPPBX2；Similarly, IPPBX2 leads to 2 audio-frequency information of opposite end meeting room that stereo process generates
It crosses meeting room bridged appearances and is sent to IPPBX1.
Step S350: the stereo process of meeting room bridge joint, IPPBX1 will receive 2 audio-frequency information of meeting room come and local meeting
Discuss room 1 each route input audio information carry out meeting room stereo process, IPPBX2 will receive come 1 audio-frequency information of meeting room and
Each route input audio information of local meeting room 2 carries out meeting room stereo process.The meeting room stereo process of IPPBX1 is specific
Include: IPPBX1 by the linear speech format for being all converted to internal unity per input audio all the way in meeting room 1, comes receiving
2 audio-frequency information of meeting room be also converted into the linear speech format of internal unity, then the audio-frequency information converted is understood
Room stereo process is discussed, the audio-frequency information after generating meeting room bridge joint, this audio-frequency information is linear speech format.It then will be after audio mixing
Audio-frequency information be reconverted into the corresponding phonetic matrix of each input channel, former road is distributed away.Due to stereo process at this time
It is identical as plain old telephone meeting stereo process, therefore specific processing mode repeats no more.Similarly, it can also be done at the end IPPBX2 above-mentioned
Similar processing.
Step S360: the meeting room business operation after bridge joint, IPPBX1, which is sent, carries 1 information about firms of local meeting room
OPTIONS requests to give opposite end meeting room 2 place IPPBX2, and IPPBX2 extracts information about firms therein after receiving request and shows
Show, such opposite end meeting room 2 is known that in local meeting room 1 there is which member；Similarly, IPPBX2, which is sent, carries opposite end meeting room
The OPTIONS of information about firms is requested to IPPBX1, and IPPBX1 where local meeting room does same processing.Both ends meeting room in this way
It is just aware of the information about firms of other side mutually.Meanwhile this two IPPBX can also mutually send the OPTIONS for carrying and ordering and ask
It asks, such as kicking a player, prohibits speech etc..
Step S370: meeting room bridge joint disconnects, and IPPBX1 sends BYE and requests to give opposite end meeting room institute where local meeting room
Meeting room bridged appearances are released after IPPBX2 where IPPBX2, opposite end meeting room receives BYE request.
Meeting room bridged appearances refer in above step: IPPBX1 server and meeting room 2 where local meeting room 1
A software communication channel on the IPPBX2 server at place, the channel are used to transmit 2 audio of meeting room of IPPBX2 sending
1 audio-frequency information of meeting room and various businesses request that information and various businesses request, IPPBX1 issue.
After two meeting rooms bridge successfully, meeting room information about firms can between two servers of IPPBX1 and IPPBX2
With mutually shared, herein, we illustrate so that 1 information about firms of meeting room is shared at the end IPPBX2 as an example:
At the end IPPBX1, the information about firms of local meeting room 1 is arranged by it, is saved in xml format；It is accessed by meeting room
Password encrypts the information about firms of local meeting room 1 using reversible encryption mode；Encrypted information is sent by SIP signaling
To the opposite end IPPBX2 server.
It is connect after receiving 1 information about firms of local meeting that IPPBX1 is sended over using the meeting room at the end IPPBX2
Enter password to be decrypted；The information about firms of the information about firms of opposite end meeting room 1 after decryption and local meeting room 2 is integrated and shown
Show.
In addition, after meeting room bridges successfully, different servers can the participant side directly to opposite end server carry out
The business operations such as speech are prohibited in similar kicking a player.We are carried out with participant side member of the end server ip PBX1 to the end server ip PBX2
It is illustrated for above-mentioned business operation:
At the end IPPBX1, by it according to the input of user, integrated operation order is simultaneously saved into certain format；Pass through meeting room
Access pin uses reversible encryption mode cryptographic operation order；Encrypted operational order is sent to by SIP signaling described
On the server ip PBX2 of opposite end.
At the end IPPBX2, after receiving the encrypted operational order, solved by the meeting room access pin
It is close；Operational order after decryption is authenticated, is executed, and implementing result is carried out reversible add using the meeting room access pin
It is close, feed back to the local server IPPBX1；
Local server IPPBX1 decrypts the implementing result using the meeting room access pin, result can also be shown
Show to route 1, route 2, each participant side's terminal of route 3.
As another specific embodiment of the invention, for the merging for two meeting rooms being on same IPPBX, originally
Scheme also gives following elaboration:
Step S410: firstly, then extension set 1,2,3,4,5,6 establishes meeting in IPPBX1 register account number on IPPBX1
Room 1 and meeting room 2.
Step S420: bridged appearances are established, since meeting room 1 and meeting room 2 are on same IPPBX, no longer need
It sends out and sends bridge joint request via SIP again, but voluntarily meeting room 1 and Bridge 2 are connected together by internal system.
Step S430: meeting room bridge joint communication, meeting room 1 will pass through after the audio signal mixing of participant side in this meeting room
Meeting room bridged appearances are sent to meeting room 2, while receiving the audio mixing data from meeting room 2 from meeting room bridged appearances；Similarly,
Meeting room 2 will be sent to meeting room 1 by meeting room bridged appearances after the audio signal mixing of participant side in this meeting room, while from
Meeting room bridged appearances receive the audio mixing data from meeting room 1.
Step S440: the stereo process of meeting room bridge joint, meeting room 1 will all be converted to internal unity per input audio all the way
Linear speech format, the audio-frequency information for receiving the meeting room 2 come is also converted into the linear speech format of internal unity, then
Stereo process is done to the audio-frequency information converted, the audio-frequency information after generating audio mixing, this audio-frequency information is linear speech format.
Then the audio-frequency information after audio mixing is reconverted into the corresponding phonetic matrix of each input channel, former road is distributed away.Similarly, exist
Meeting room 2 also does above-mentioned similar processing.
Step S450: the meeting room business operation after bridge joint, since meeting room 1 and meeting room 2 are on same IPPBX,
Therefore, this step no longer needs to send OPTIONS request.Internal system directly closes the information about firms of two meeting rooms
And.Meeting room 1 and meeting room 2 directly can mutually see that other side's information about firms, IPPBX1 can also be directly to meeting room 1 and meetings
The member discussed in room 2 carries out business operation.
Step S460: meeting room bridge joint disconnects, and IPPBX1 releases meeting room bridged appearances, at this point, meeting room 1 and meeting room
Without special contact channel between 2, the sound of other side can not be mutually heard.
Two IPPBX are used interchangeably Session Initiation Protocol in the present invention, and meeting room bridge joint request is used in the step S310, by
There is no meeting room bridge joint request in traditional Session Initiation Protocol, therefore the present invention needs to be extended to the INVITE request in SIP,
With difference tradition request.
Traditional INVITE requested part is as follows:
INVITE sip:6301@192.168.124.154 SIP/2.0

In addition the present invention adds head file: X-Grandstream-Mcb-Req:$ in traditional INVITE request
{ CONF_HASH:40 } $ { SHA1_PASS:40 }, wherein CONF_HASH: local meeting room number (is wanted using hash algorithm
The local meeting room of merging) character string packed, SHA1_PASS: using hash algorithm to opposite end meeting room access pin
The character string packed is transmitted in a network in plain text to avoid sensitive information, reinforces safety.Opposite end IPPBX is received
After INVITE request, judge it is meeting room bridge joint request according to X-Grandstream-Mcb-Req field, then to X-
SHA1_PASS character string in Grandstream-Mcb-Req checked, if character string correctly if password authentification pass through.
CONF_HASH field is checked whether there is in the local database simultaneously, is had, and illustrates that merging request meeting room has been in bridge
State is connect, cannot repeat to bridge, refusal request is directly hung up；It does not add the field in the database then, continues subsequent processing.
It needs to delete the field from database when bridging and releasing.
" OK " response code is used in above-mentioned steps S320, the present invention is receiveed the response to traditional SIP " OK " and is extended, tradition
SIP responds as follows:

The present invention is receiveed the response in tradition adds a head file in body:
X-Grandstream-Mcb-Resp: ${CONF_HASH}
Wherein CONF_HASH: opposite end meeting room number (the opposite end meeting room to be merged) is carried out using hash algorithm
The character string of packaging.
After local meeting room receives response, check that the response is meeting room bridge according to X-Grandstream-Mcb-Resp
The corresponding response code of request is connect, then searches CONF_HASH field in the local database, then there are data by the field
In library, have, illustrates to have bridged, directly hang up.It needs to delete the field from database when bridging and releasing.
OPTIONS request is used in above-mentioned steps S360, this requests to belong to the extended requests of Session Initiation Protocol, same reason,
We need to customize the OPTIONS request for being specific to meeting room bridge joint, to distinguish traditional OPTIONS request.
Traditional OPTIONS request:
OPTIONS sip:carol@chicago.com SIP/2.0

Content-Type : application/sdp
Content-Length: 0
When OPTIONS carries information about firms, the present invention changes Content-Type:application/sdp field into
Content-Type:application/X-Grandstream-Mcb-info
X-Grandstream-Mcb-info indicates that this OPTIONS belongs to meeting room bridge joint, and the data carried are XML
Format, this XML data are meeting room information about firms.Such as:
<?xml version="1.0" encoding="UTF-8"?>
<Meeting-room ID = “6300”>
<User1 number = “1000” channel = “SIP/1000-00000003” time = “00:20:
00”></User1>
<User2 number = “1001” channel = “SIP/1001-00000003” time = “00:30:
00”></User2>
</Meeting-room>
Judge that this OPTIONS belongs to meeting according to X-Grandstream-Mcb after IPPBX receives OPTIONS request
Then room bridge joint starts to parse meeting room information about firms in additional XML data, it may be necessary to store this information.In addition, into one
Step provides the realization using opposite end access pin XML, avoids plaintext transmission.
When OPTIONS carries control command, the present invention changes Content-Type:application/sdp field into
Content-Type:application/X-Grandstream-Mcb-command。
X-Grandstream-Mcb-command: indicate that this OPTIONS belongs to meeting room bridge joint, and the data carried
It is command information, saves in xml format.Such as:
<?xml version="1.0" encoding="UTF-8"?>
<Command content = “meetme kick 6300 1000”>
</Command>
Or
<?xml version="1.0" encoding="UTF-8"?>
<Command content = “meetme mute 6300 1000”>
</Command>
This OPTIONS is judged according to X-Grandstream-Mcb-cammand after IPPBX receives OPTIONS request
Belong to meeting room bridge joint, and the information carried is command information.Then start resolve command and execute order.Further give
Out using the realization of opposite end access pin encryption XML, plaintext transmission is avoided.
Fig. 4 show the server capability frame diagram in the specific embodiment of the invention with meeting room bridging functionality.In order to
It realizes meeting room bridging functionality of the invention, should support following operational module simultaneously in the both ends server for carrying out communication bridge joint
Function.It can be seen that IPPBX server includes: signaling communication module, bridge joint control module, meeting room bridged appearances, mixes
Sound processing module, and local meeting room.
Wherein, signaling communication module for sending meeting room bridge joint request to other side IPPBX server, or receives and
It requests and parses from the meeting room bridge joint of other side.For example, the signaling communication module in IPPBX1 sends meeting room bridge to IPPBX2
Request is connect, invites meeting room 2 that meeting room 1 is added, then waits the response of meeting room 2, it is attached in the bridge joint request of above-mentioned meeting room
Authentication information with meeting room 2.Signaling communication module can check whether request type is that meeting room bridge joint is requested and checked
Whether its authentication information is correct, loopback " OK " answer back code when request type and all correct authentication information.Above-mentioned bridge joint request letter
Order is the meeting room bridge joint request of an extension, i.e., a custom field is added when INVITE is requested, and calculate using Hash
Method the local meeting room number is packed after demand signalling.In addition, the signaling communication module be also used to receive or
The OPTIONS request for carrying local meeting room information about firms is sent, traffic signaling therein is transferred to bridge joint control after parsing
Molding block is further processed.
Control module is bridged, bridge joint signaling is received and processed from signaling communication module, is responsible for establishing or disconnecting meeting
Room bridged appearances.For example, the signaling communication module confirmation other side's request type and authentication information of IPPBX2 all correctly can then reply
IPPBX1, while if IPPBX1, which receives " OK " response and parses, is confirmed as meeting room bridging type, mould can be controlled by bridge joint
Block establishes meeting room bridged appearances.Meeting room bridge joint is disconnected to IPPBX2, notice IPPBX2 when IPPBX1 sends " BYE " request,
After IPPBX2 receives " BYE " request of IPPBX1, bridged appearances are released.
In addition, being connect after the bridge joint control module receives the request of the OPTIONS from signaling communication module by meeting room
Enter password decryption to extract information about firms therein and export display, such opposite end meeting room is known that in local meeting room which has
A little members；Similarly, the OPTIONS that IPPBX2 sends carrying opposite end meeting room information about firms requests to do together to IPPBX1, IPPBX1
The processing of sample.Both ends meeting room is just aware of mutually the information about firms of other side in this way.At this point, above-mentioned bridge joint control module can also incite somebody to action
Local meeting room information about firms is sent after being encrypted using reversible encryption mode by signaling communication module by meeting room access pin
