    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:
    upload_2017-3-9_12-55-35.png
    This is the Zoom setting screen
    upload_2017-3-9_12-54-26.png

    And it registers correctly:
    upload_2017-3-9_12-56-48.png

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

    Why would incoming calls work fine but outgoing calls not?

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