Add SipHeader to all extensions (PJSIP)

Dear Community,

To simplify this case I have to add:


header to all incoming calls (PJSIP).
I have GDS3710 intercom and 2 devices. I’m using GSWave app.
Everything works except bloody “Open door” button - which is not visible.
Sending this header hopefully resolve my problem.



What about sip proxy server?
Instead of manipulating SIP Headers in freepbx and asterisk, can I just install
proxy server and manipulate SIP requests?
Does it make sense?

Check out the “Hooking for fun and profit” Hooking for fun and income article @lgaetz wrote last year. That should get you started.
