Re: [OpenSBC] OpenSER and OpenSCB as outbound proxy

[ehernaez <ope...@op...>]

The short answer to your question is that OSBC uses the to-uri for all routing.  So, if you want to use it for NAT traversal, the registrar must put the AOR in the to line.   There are changes underway that will allow more granular routing rules in OSBC, but it's not there currently.


Also, when performing Upper Registration, OSBC uses the base SIP port plus 60020 as a back-door in order to recognize calls for which itshould have a local registration.  This explains whythe AOR seen in SER was 65086.
