SIP2SIP

Asterisk PBX

The SIP2SIP platform consists of several servers, addressed by DNS SRV records. Asterisk, however is currently unable to handle more that one result for a DNS SRV lookup, so the configuration needed for getting it work with the SIP2SIP service is a bit confusing. This wiki page helps clarify that hopefully.
