look in do_invite in sofia_glue.c you have plenty of things you can modify with just variables but be warned you'll break a lot of things if you change stuff beyond what works.

Hello Chad,

I guess you are not supposed to do that because you must only use the
standard headers, otherwise you could have compatibility issues.

Use

<action application="set" data="sip_h_X-myheader"/>


To create your own standard headers. If you still want to create your own
headers I'm afraid you are gonna have to patch the mod_sofia.

Best Regards.
