Hi Anton,

it seams that your opensips proxy generates the 404 - replies are not by default sent, so it must have been sent from script. I suspect your sequential requests are not properly handled and it hits the lookup(location) (which is for initial requests).

Bogdan

Hi Bogdan.

I fixed the B2B loop, but openSIPS still replies 404.

Please see on fragments on my SIP trace:

SIP flow: UA1 (192.168.0.1) -> openSIPS(B2B) (192.168.0.10) -> AudioCodes
mediant (192.168.0.20) -> UA2 (somewhere)

After negotiation:

And BYE:

And, openSIPS replies to B2B '404'


I see 2 potential moments:
1) I'm changing 'From' field on stage 2. 2) On stage 3 a field 'Contact' is "Contact:
<sip:192.168.0.10:5060;transport=udp>" althought I defined
"modparam("b2b_logic", "server_address", "sip:[email protected]")"

Hi Anton,

The ERROR line you have here are not essential - they simply say that
the warning (optional) hdr was not added. Not an actual error.

Can you check doing a capture at net level who is generating the 404
reply? from opensips script, for final callee ?

Regards,
Bogdan

Hi.

While using B2B when callee ends an established call openSIPS replies
'404
Not Here' and goes to the infinitive loop..

Here is a part of a log:

Any suggestions?
