Hi All, I am attempting to configure an AAPT IP based trunk in 3CX via a dedicated TPG SIP service, and am struggling to get it working.
What I really am after is examples of working AAPT trunk configurations that I can compare my set up to.
If anyone out there could provide some examples of correct trunk configuration, I would be extremely grateful.
Wireshark shows OPTIONS messages successfully hitting the phone system from TPG SIP server, and 200 OKAY messages being sent to TPG SIP server.
- 3CX on premise
- Wireshark shows OPTIONS being received and 200 OKAY being sent to/from TPG SIP IP
- Dual WAN connection with dedicated SIP service on WAN2
- NAT on WAN2 to local IP of 3CX
- Static routes are configured to route required SIP traffic in/out via either WAN1 or WAN2 depending on what port is required
