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?
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?
Cheers,
Daniel
