Hi all, Im looking to make a call request using the Python pjsua module with a modified INVITE line. INVITE sip:8048 at 172.0.0.10:6050;ID=241;Code=5421 Note the ID and Code parameters. It is very important for my use case that they be on the same line as the INVITE. From my reading it looks like this *might* be implemented through pjsua_acc_config.contact_uri_params but I'm not fully sure. Would be very grateful for any insight on this. Thanks much, -Ian
