FYI.

The example in AMX-PI for the commands necessary to set up paging all panels is incorrect. The RX UDP port in the example is zero for all three panels, but (in my experience, frustration, and several hours lost) must be something not zero.

The above is incorrect. It should be

I've found several other minor typos in the (skimpy) documentation for intercom functionality. You would think for such a high-profile feature there would be better support. Even tech support's official line is "use the module".

That being said, after getting the commands correct, the intercom works very well! I was amazed after wading around in the AMX UI module to look in PI and find there are only 3 real commands for intercom on the TPs (^ICS, ^ICM, ^ICE).

    I haven't tried to roll my own but the module worked fine.
    I was also impressed with the audio quality.

    Entry Communicator call setup

    FYI take 2.

    The example in the documentation for setting up an intercom call between an MET-ECOM and a touch panel is incomplete. The available <mode> parameters in the documentation are TALK or LISTEN. These work, but not to set up a two-way call. The BOTH command is what is needed.

    SEND_COMMAND MET1, "?STREAM-SET 192.168.0.3,9000,9002,audio,BOTH,1?"

    Syntax:
    SEND_COMMAND <DEV>,"'STREAM-SET <dest addr>, <dest port>, <source port> <stream type>, <mode>, <stream id>'"

    Variables:
    ? <stream ID> integers are from 1-20.
    ? <mode> Starts a call to the specified IP address and ports, where initial mode is either TALK OR LISTEN. Please note, however, that no data packets will actually flow until the intercom modify
    command below is received.

    Example (audio stream):
    SEND_COMMAND MET1, "?STREAM-SET 192.168.0.3,9000,9002,audio,TALK,1?"
    SEND_COMMAND TP2, "?^ICS-192.168.0.4,9002,9000,2?"

    Sets up a hands-free unicast call between Metreau Entry Communicators and a touch panel.
