Polycom And SIP Message

Hi all,

I want to send a text message to a polycom phone. I know how to create a call file – but that will “call” the phone and nothing happens till the phone is answered.

How do I create a call file that will “send” a text message over SIP to the polycom phone?
So the phone does not have to answer – just shows the message.

Thanks,

Jerry

  • What is the SIP command you need to send?

    Is it a simple “send and you’re done” or is there any sort of acknowledgement you need to get back again?

    Because it messes up the order in which people normally read text.

  • I presume it would just be sending a SIP message – no need to get anything back. Just want to pop a message on the phone.

  • Yes, but *what* message do you need to send?

    How does a Polycom do this?

    Without knowing that, I don’t think we can work out how to ask Asterisk to do it.

    Douglas was one of those writers who honourably failed to get anywhere with
    ‘weekending’. It put a premium on people who could write things that lasted thirty seconds, and Douglas was incapable of writing a single sentence that lasted less than thirty seconds.

  • I think there are some Polycoms that support RFC 3428 SIP MESSAGE for instant messaging eg. Kirks.

    Also how long should it display for, do you want a sound to play, should it interrupt users currently on a call, present an interface to acknowledge the message, etc.

    Disregarding RFC 3428 method, for SPIP, VVX, and probably a few other Polycom models, you can push XML to the phones via HTTP using something like CURL…

    Here’s some Asterisk dial plan example (but put this all on one line):

    exten => s,n,TrySystem(
    curl
    –max-time 1
    -d
    “hi.php”
    -u “push_username:push_password”
    –digest
    -H “Content-Type: application/x-com-polycom-spipx”
    http://192.168.1.100/push
    );

    You’ll need to update the IP to match your phone, run a webserver to host hi.php, and set a few things up in your Polycom configs, such as push_username and push_password, but hopefully that helps pop you in the right direction.

    Regards,
