[This email is resent for the last one is oversized] Hi Bodgan,
Thanks a lot for the help, the pcap file is attached. The call flow is as -
#11. INVITE from the caller on 10.10.8.131 to B2BProxy
10.10.9.205
#15. Forwarded INVITE from B2BProxy with the expected To
header to SIP UA1
.. . the call is setup and then b2b_bridge is triggered ...
#75. B2BProxy sent reINVITE to the caller
#77. B2BProxy sent INVITE to SIP UA2 with the unaccepted To
header
#79. SIP UA2 rejected the call
The step #77 And #79 shows the problem, that the call was rejected as the To
header in INVITE is not using the UA2's IP instead of B2BProxy's IP as domain
name, which is required in our system.
In our opensips.cfg script, we have already included clauses like
remove_hf("To") and append_hf("To ...") but seems like they only work before
b2b_bridge occurs.
Thanks,
Li

Hi Li,
Somehow we are going in circles here :). So, could you post a pcap for call
going via your B2B (showing all in and out SIP messages) and mention which
frame is the outgoing request you cannot modify ?

Hi Bogdan,
Thanks for the explanation. I mean that the local_route can take effect for the
forwarded INVITE(from incoming ones) in our proxy, but not after b2b_bridge.
I'll do more debugging on it since the messages should be visible. Thank you
very much.
Thanks,
Li

Hi Li,
All SIP requests generated by `b2b_bridge` are to be visible in local_route.
And on the contrary, the incoming (received) requests DO NOT trigger local
route.

Hi Bogdan,
Yes, we have put the changes by calling remove_hf() and append_hf() in the
'local_route', those functions for new incoming INVITE but not the INVITE sent
out by 'b2b_bridge'.
Thanks,

Hi Li,
Have you tried to use the local_route in order to do custom changes on the
outgoing requests generated by the B2B bridging ?

Hi,
I'm working on a change for a B2BUA based on OpenSIPs 2.4, but not sure if the
function is supported or if it has been supported in the later versions.
We have used the MI command b2b_bridge to bridge existing calls from one entity
to another and it works, the scenario is the same as expected. While besides
this, we also need to modify one of the headers of the INVITEs sending to the
new destination in this scenario, our scripts in the opensips.cfg can't take
any effect.
Thanks,
Li
