Hi Li,
The INVITE in #77 is an initial INVITE, connecting to a new party (as a result
of the bridging), so the TO hdr in that INVITE is dictated by the B2B logic -
as you can see the TO URI is the same as RURI, pointing to the new party in the
bridging.

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,
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

Re: [OpenSIPS-Users] Modify the headers after executing a MI function in B2B_LOGIC module
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.
