Hello. I try to provide call scheme:
internal client -> asterisk -> Kamailio -> provider -> external endpoint
call
when I make call I see this:
asterisk kamailio provider
invite --> invite -->
<-- 407
ACK -->
invite w/Auth -->
<-- 100 <-- 100
<-- 180 <-- 180
<-- 183 <-- 183
<-- 200 <-- 200
ACK --> ACK -->
My problem with last ACK, that I send to provider. Provider ignores it, and
sends me some OK packets. As resultI can notend session ( answer to BYE 481
- transaction does not exists). I think it is wrong ACK but can not
undrtand where I do mistake.
Please help me to find it:

So after this ACK provider still sends me 200 OK and my server still sends

tags and call-id always one.
Thanks
