Hi everybody!
I am using FreePBX 2.11 on top of Asterisk 11.7.0
Everything works as expected except of sending a Custom CID (in detail adding the extension number for outgoing calls). When i asked my provider, they said that this is possible and sent me a short configuration example for asterisk 1.4
extension.conf
;--- Outbound ---
SIPAddHeader("P-Preferred-Identity: ")
Dial(SIP/thenumbertodial@neotel)
After some search I found out that “SIPAddHeader” can not be set by FreePBX GUI. Up to now I only configured the PBX with the GUI but now I have to edit files manually but I do not understand the Asterisk syntax in detail.
Currently Outbound CID (users), Route CID and Outbound CID (trunk) are blank.
Maybe someone could help me.
