[SR-Users] TOPOS contact issue on RE-INVITE

[Daren FERREIRA]

Hello Daniel,

Thanks for your reply, i saw your thread, it seemed to be solved with last updates, so i was confident in keeping trying… :)

So i’m wondering what is the best solution for topology hiding.

It is changing from time to time:

- Kamailio + Freeswitch : but in this case, outgoing requests are done with freeswitch which seems much less performant than Kamailio for gateway dispatching according to their availability, their load and so on
- Kamailio + SEMS SBC module : but it seems to be no more maintained (replaced by commercial ABC SBC from TRAFOS)

Kamalio is very good for a lot of things, and would be perfect if it might better manage topology hiding, as TOPOS begin to be able to do.

In my case i suppose that is related to topos not to manage multiple branches, or more precisely, not doing its direction detection, that seems to be the most influencing parameter for him to know which domain to use on forwarder requests.
As, if i well understood, re-invite is an new branch, or maybe there is something to do in the routes to help TOPOS knowing what to do…

Maybe Daniel (miconda) has some ideas on that, as we already fixed some TOPOS problems in the past…

Best regards
