[Freeswitch-users] TCAPI_User in Contact

[João Mesquita]

The answer to this one was not all that easy because it is hidden on the source code and undocumented as far as I can tell.






sofia_glue.c has a function called sofia_glue_do_invite. Right there is where all this is generated and you can pretty much change any header you want using channel variables. The contact relevant ones you are looking for are:






sip_invite_contact_params

sip_contact_user




contact_params is what goes after the URI (after the ;) and the contact_user is 5122046107 (mailto:5122046107 at 74.37.201.198), which in your case you want to change to TCAPI_User.

What I would really ask you to do is to go ahead and document those on the wiki, please. A lot of these variables are not documented anywhere and few ppl know of their existence.

Regards,
