Hello Mihai,
your trace just shows the INVITE, 100, 183. There is no 200 OK, therefore also no ACK.
Is there some thing missing? Does the called side actually accept the call?
Cheers,
Henning

Well, i've tried both opensips and kamailio but with kamailio i got the most far.
Bellow it's a trace of an outgoing call, the trace is from kamailio box.
Legend: 10.1.1.10 is the Asterisk Box, 10.1.1.4 is Kamailio.

Have you tried changing the trunk's name from opensips-trunk to kamailio-trunk?
On the serious side, a SIP trace would help.

Hi all,
I've tried to create a reverse proxy to forward incoming request that came from SIP provider to Asterisk PBX and forward the requests from asterisk to kamailio then sip provider.
What i get is that I see the invite, but is like no ACK.
Thanks in advance.
