6. The method according to claim 1, wherein the enabling of the connection between the terminal and the conference system according to the conference call information and/or the invitation to join comprises:

acquiring conference call information of an intranet terminal;

determining that the network conference number in the conference call information corresponds to the cloud video platform, and determining an external network number corresponding to the network conference number through pre-configured number mapping;

and forwarding the conference call information to the cloud video platform through a second pass-through packet of the SBC based on the external network number.

7. The method according to claim 1, wherein the enabling of the connection between the terminal and the conference system according to the conference call information and/or the invitation to join comprises:

acquiring conference call information forwarded by an external network terminal through a first pass packet of the SBC;

8. The method of any one of claims 4-7, further comprising determining that the netmeeting number corresponds to a cloud video platform and/or an internal conferencing system based on a meeting prefix of the netmeeting number.

9. The method according to any of claims 4-7, wherein the pre-configured number mapping comprises associating stored extranet and intranet numbers.

10. The method of claim 1, wherein the enabling the connection of the terminal with the conference system according to the pre-configured agent registration information comprises:

acquiring conference invitation information of an internal conference system;

searching a terminal address of a target terminal corresponding to the conference invitation information in pre-configured agent registration information;

and determining that the terminal address is an external network identifier, and sending the conference access invitation information to an external network terminal through the first traversing packet of the SBC.

11. The method of claim 1, wherein the enabling the connection of the terminal with the conference system according to the pre-configured agent registration information comprises:

acquiring conference invitation information of an internal conference system;

and determining that the terminal address is an intranet identifier, and sending the meeting invitation information to an intranet terminal.

12. The method of claim 1, wherein the enabling the connection of the terminal with the conference system according to the pre-configured agent registration information comprises:

acquiring conference invitation information of the cloud video platform forwarded by the second traversing packet of the SBC;

13. The method of claim 1, wherein the enabling the connection of the terminal with the conference system according to the pre-configured agent registration information comprises:

and determining that the terminal address is an intranet identifier, and sending the conference entrance invitation information to an intranet terminal through the first traversing packet of the SBC.

14. The method according to any one of claims 10 to 13, wherein the preconfigured proxy registration information includes a terminal address and an intranet identifier or an extranet identifier corresponding to the terminal address.

15. An apparatus for implementing a session initiation gateway, the apparatus comprising:

16. An apparatus, characterized in that the apparatus comprises:

one or more processors;

a memory for storing one or more programs;

when executed by the one or more processors, cause the one or more processors to implement the session initiation gateway implementation method of any one of claims 1-14.

17. A system is characterized by comprising a session initiation gateway, a Session Border Controller (SBC), an external network terminal, an internal conference system and a cloud video platform; the session initiation gateway is respectively connected with the intranet terminal, the internal conference system and the SBC, and is configured to implement the method according to any one of claims 1 to 14;

the SBC is respectively connected with the cloud video platform and the external network terminal, wherein the SBC is configured with two traversing packets, the first traversing packet is used for data interaction between the external network terminal and the internal network, and the second traversing packet is used for data interaction between the external core network and the internal network.

18. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out a session sending media gateway implementation method according to any one of claims 1 to 14.
