For the first Invite, I received an “503 Service unavailable” from the gateway , it goues trough the SBC and it is pass to the LCR so it reroutes the call to the second gateway in the cloud. I asked in FreeSWITCH forum for this issue and they said that the problem is Cseq not increasing, Freeswitch doesn’t take Ruri as compare.

I have this structure: * * When I make a call from one client connected to LCR, it is route to my SBC and afterwards to his destiny in the cloud passing though a gateway. When the destiny is unreachable, the LCR reroutes the call to another gateway. Sometimes the LCR send this retry again to the SBC , because the second gateway is also in the cloud, but when this happens, FreeSWITCH answer with : “482 Request merged” because it detects that is the same call. This is because the second INVITE has the same Call-ID and same Cseq. Kamailio *is not* increasing CSeq. Is there a way to resolve this? it is a second branch, the top via header of the second invite should have a different branch parameter than the previous one. Freeswitch should detect that and handle it as a separate branch of the call, too. Try changing the r-uri a bit and see if works (e.g., set a prefix that you remove it if set), as an workaround. Also, is the CANCEL sent to Freeswitch for first branch? Or is Freeswitch sending a negative reply?
