FreePBX line to 3CX

FreePBX Endpoints
1

Hi,

I am linking a 3CX to a FreePBX using bridging from 3CX as outlined in this guide;

Calls placed from the 3CX to the Asterisk give a “403 forbidden” from the Asterisk IP address and the Asterisk reports;
“sip rtp tos bits 184
sip rtp cos mark 5”
Calls placed from the Asterisk to 3CX establish and function correctly.

Any thoughts are greatly appreciated.

Thanks

Mike

I dont use a register string on mine and i have type set to friend. Works fine. I also use IP authentication so no username and password and I don’t use the 3cx bridge. Its just a plain trunk.
