Is it possible to add custom field to SIP header? I need to add field "X-Fid" with OutboundCallerId value.
In asterisk I had:
"exten => _X.,1,SIPAddHeader(X-Fid: ${SIPCALLID})"
Hi there,
Unfortunately you can't add such field, there is a predefined list of fields which can be set through your voip provider settings / Outbound Parameters tab.
