Hi all,

I’m working for a while with Kamailio+Freeswitch as SBC.

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?
