Re: [pjsip] SIP INVITE/ACK and SDP (2)
What about the on_call_sdp_created callback of the pjsua_callback?
Documentation tells:
Notify application when a call has just created a local SDP (for
initial or subsequent SDP offer/answer). Application can implement
this callback to modify the SDP, before it is being sent and/or
negotiated with remote SDP, for example to apply per account/call
basis codecs priority or to add custom/proprietary SDP attributes.

Hi Jérôme,
this can be achieved by using an appropriate pjsip_module with the right priority.
Check the sipecho sample for illustration purpose.
Cheers,
Alain

Hi,
Following my previous message, I made a mistake : It is precisely not about the ACK(180), but the OK(200).

you can also use that approach. You stated previously: "I would like to
modify some SDP parameters of the ACK before it is sent, like IP
addresses and ports, because for some reasons, the receiver of the
media will not be the one running pjsip". With the pjsip_module though,
you would have a broader control over the resulting buffer that is sent
to the peer.But for most cases altering the SDP in on_call_sdp_created
is fully sufficient.
Cheers,
Alain
