A service provider requires me to send a P-Asserted-Identity in INVITES. If i set send_pai=true the P-Asserted-Identity header is not added. Is there something else i need to do to enable PAI ?
I do understand Asterisk 13 is no longer supported.
I am definitely using the correct channel driver (PJSIP) and the right endpoint. Are there any other settings that are conditional to allow the PAI header to be added to INVITES ?
