Free PBX trunked to Soft Switch

I recently configured an additional SIP trunk on my free PBX ver:2.2 looking to my Soft switch and am currently only able to send/route calls from the Free PBX- Soft Switch, I am unable to recieve inbound calls that are routed from Soft Switch-Free PBX.

Could this be result of incompatibility between the free pbx and soft switch…

btw.I’m using a X-Rainbow ver:5.0 platform for the soft switch.

Let me know if you need additional information to assist

Thanks in advance

It’s more than likely the result of you incorrectly registering with your softswitch.

Asterisk supports all standard SIP peering methods and is generally easiest to configure as a B2BUA.
