Abstract
The invention relates to the field of network voice communication terminals, in particular to a method for automatically switching an address of an external proxy server. In step 4, if a domain name address of the external proxy server is not a domain name, an IP (internet protocol) address is used for registration, and if registration succeeds, calling is made. In step 5, if the registration of the address fails or no response is received during calling, the address of the external proxy server is switched; if a plurality of IP addresses are stored, the address is switched to the next, but if the currently-used address is the last one, domain name resolution is performed again to acquire the address. The method has the advantages that when one external proxy server breaks down, the address of the external proxy server is not required to be configured and modified manually, so that the circumstance that all the agent equipment cannot be used due to failure of one external proxy server is avoided.
Description
Technical field
The present invention relates to network voice communication (voice over internet protocol is called for short VOIP) terminal field, relate in particular to a kind of method of the external proxy server address of automaticallying switch.
Background technology
Along with popularizing of communication and network, this talking mode that is different from traditional public switched telephone network (Public Switched Telephone Network is called for short PSTN) of VOIP has obtained increasing application chance.Particularly under the policy of country " light advances copper and moves back " and country's " unification of three nets " was guided, the VOIP technology had obtained unprecedented development opportunity, and the VOIP phone also begins to enter huge numbers of families.
The VOIP phone is the function that realizes by principal and subordinate's form, will register to server earlier before use, only under situation about succeeding in registration, a series of associative operation such as just can call.All directly be sent to registrar and acting server if register and call, then the task of this two server is just heavy especially, in order to alleviate the task of this two server, then sets an external proxy server in a specific region and handles this type of event.When we initiate registration and call out, send to external proxy server earlier, handled by external proxy server again, transmit.The final realization registered and called out.
In present practical application, as Fig. 1, this external proxy server address, all be to use with the form of domain name, after setting, just be inconvenient to change, if run under the situation that acting server breaks down, then by this external proxy server agency's all devices cisco unity malfunction all, influence big especially.May have standby external proxy server or have other external proxy server to exist this time, if the normal merit work of the equipment that will use this section can only be served the product configuration item by manually going the external agent who revises each client.

The object of the present invention is to provide a kind of method of the external proxy server address of automaticallying switch, solved and be inconvenient to change the problem that the coverage that breaks down is too big after present external proxy server address sets.
For addressing the above problem, the technical solution used in the present invention is:
A kind of method of the external proxy server address of automaticallying switch may further comprise the steps:
Step 1 disposes a fixed outer acting server domain name addresses that can parse a plurality of IP;
Step 2 judges whether the external proxy server domain name addresses is domain name;
Step 3 if the external proxy server domain name addresses is domain name, is then carried out address resolution to domain name, chooses the address of limit priority as the external proxy server address that is used for initiating registration;
Step 4 if the external proxy server domain name addresses is not domain name, is then gone registration with this IP address, if succeed in registration, makes a call;
Step 5 if address registration is failed or do not obtained responding, is then carried out the external proxy server address switchover when making a call, the IP address that preserve this moment has a plurality of, then switch to the next one, if the address of using has been last now, then carries out domain name mapping again and obtain the address.
Further technical scheme is, in the described step 3, it is unsuccessful that domain name is carried out address resolution, then carry out the external proxy server address switchover, the external agent address that preserve this moment has a plurality of, then switch to the next one, if the address of using has been last now, then switch to first external proxy server address again.
The method that a kind of VOIP terminal system automatic switchover external proxy server is initiated registration and called out may further comprise the steps:
Step 1 disposes a fixed outer acting server domain name addresses that can parse a plurality of IP;
Step 2 judges whether the external proxy server domain name addresses is domain name;
Step 3, if the external proxy server domain name addresses is domain name, then domain name is carried out address resolution and the priority orders of a plurality of IP address of this domain name correspondence when returning preserved, choose the address of limit priority as the external proxy server address that is used for initiating registration;
Step 4 if the external proxy server domain name addresses is not domain name, is then gone registration with this IP address, if succeed in registration, makes a call;
Step 5, if address registration is failed or is not obtained responding when making a call, if this moment, IP also had remaining IP address to use in lining up, if have then from tabulation, obtain next IP address and be set to current external proxy server address, do not switch if then carry out external proxy server, the IP address of preserving this moment has a plurality of, then switches to the next one, if the address of using has been last now, then carries out domain name mapping again and obtain the address.
Further technical scheme is, in the described step 3, it is unsuccessful that domain name is carried out address resolution, then carry out the external proxy server address switchover, the external agent address that preserve this moment has a plurality of, then switch to the next one, if the address of using has been last now, then switch to first external proxy server address again.
The beneficial effect that adopts technique scheme to produce is: the present invention can be therein under external proxy server situation about breaking down, manually configure is revised the external proxy server address, but the mode by domain name, allow a fixed domain name address resolution become a plurality of IP, when a corresponding acting server of IP breaks down, can switch to next IP address automatically registers and makes a call, can not influence client's normal use like this, avoided making all out of use problems of its all devices of acting on behalf of because an external proxy server breaks down.Description of drawings
Fig. 1 is the schematic flow sheet that a kind of VOIP terminal system automatic switchover external proxy server is initiated the method for registration and calling.
