SIP2SIP

== Asterisk PBX ==

The SIP2SIP service platform consists of several OpenSIPS servers running in difference data centers using SIP Thor distributed architecture, which is using servers, addressed by DNS SRV records to point to the actual servers. records. Asterisk, however is currently unable to handle more that one result for a DNS SRV lookup, and so the Asterisk configuration needed for getting it work with the SIP2SIP service is not trivial. a bit confusing. This wiki page helps clarify it. that hopefully.
