Description

The Enhancement Method and terminal locally survived
Technical field
The invention belongs to the communications field, more particularly to a kind of Enhancement Method and terminal locally survived.
Background technology
In the speech network of general headquarters+branch, when general headquarters' speech network is normal, general headquarters control exhaling for its terminal managed Cry, terminal can enjoy the business (such as the business such as meeting, recording) of general headquarters' offer；In general headquarters' speech network failure, branch's energy Speech network is capable of the calling of adapter branch terminal, and such a mode is referred to as local survival.
When general headquarters' speech network is normal, branch's session initiation protocol (English：session initiation Protocol, referred to as：SIP) endpoint registration is to headquarters server, if branch's speech network supports local survival, when general headquarters' voice After network failure, branch's sip terminal is registered to the access device of branch's speech network, and branch's sip terminal is registered to branch's voice After the access device of network, branch's sip terminal can realize the INCOM intercom of branch's speech network, and pass through branch's speech network Access device be connected to PSTN（English：Public switched telephone network, referred to as： PSTN）Network.
Internet protocol（English：Internet Protocol, referred to as：IP）Terminal is by being locally configured or domain name mapping Get call server address, call server address then disposed by the configuration management interfaces of IP terminals, general headquarters+point In branch pattern, generally logical IP terminals cross domain name system（English：Domain Name System, referred to as：DNS）Server is obtained and exhaled Server address is, but IP terminals now can not obtain customer terminal equipment by DNS（English：Customer Premise Equipment, referred to as：CPE）Address, so CPE can not realize local survival.
