Connected an 3rd party PBX like Asterisk on our 3CX server via a SIP trunk. Now, when the Asterisk PBX makes a call outside comes in as an incoming call to our 3CX since a SIP Trunk requires a "Default route" which is by default an extension. How can the "Default route" be routed to the Outbound Rule, as currently it just goes to voicemail.
