Hello,
I have the following topology.
Kamailio as SIP Proxy and Asterisk as B2BUA. In Kamailio I use
rtpproxy for NAT users.
The problem that I have is the following:
-When the CSipSimple is registered the first call is always
unsuccesfull. The following calls are always successful. If the
application remains idle for a while the next call is unsuccessful
again. From traces I saw that everything is OK in signaling part.
-When I try with Zoiper and 3CX I have 1/20 successful calls.
In any case from Asterisk side these calls can be seen as active but
no media.
maybe providing the sip trace will help us to see if something is wrong
there. Otherwise, it is hard to guess what is wrong, can be the nat
router in front of the phones, doing 'smart' sip alg.
Cheers,
Daniel
Thanx,
Theo
