ZOOM Rooms SIP integration

[andy_vdg]

Hi everyone,

I am trying to integrate Zoom Rooms with 3CX. (https://support.zoom.us/hc/en-us/ar...gest=ccc31f59e727594613a39e30b3f4bdb3ae0ce5e2)
They officially offer SIP PBX support and I've gotten the extension to register correctly.
This is the extension:

This is the Zoom setting screen


And it registers correctly:


I can call extension 242 from extension 205 and answer them in Zoom without a problem.

But when I try and call extension 205 from the Zoom extension 242 it doesn't work.

Why would incoming calls work fine but outgoing calls not?

Bump

Everything is working now.
Had to re-boot Zoom Rooms and now it is registering properly.
Make sure transport protocol is UDP.
