General Help

hi,

our SIP provider expects from us to send P-Preferred-Identity to change the CLID for a trunk. I can add Remote Party ID but they said it’s not the same.

I added following to extensions_custom.conf but no lcuk!

[from-internal-custom]
exten => X,1,SipAddHeader(P-Preferred-Identity: sip:${CALLERIDNUM})

how can i add this P-Preferred-Identity?

thx,
