Is it possible to use the instant messaging feature of Polycom phones in Asterisk? At the moment I’m seeing this in the SIP messaging when I try to send one from a Polycom 450.

<--- SIP read from UDP::5060 —>
INVITE sip:0100@:5060;user=phone SIP/2.0
Via: SIP/2.0/UDP ;branch=z9hG4bK484dcd1fDD872ECE

  • Asterisk does not understand or support an SDP media type of ‘message’.

    Both chan_pjsip and chan_sip can support SIP MESSAGE requests, received both in dialog and out of dialog. In addition, chan_sip will handle media types of ‘text’ for real-time text received in the RTP stream.

  • I didn’t know that instant messaging was a feature with the Polycom’s. Do you have any documentation, how-to’s, etc. that you can point me to? That would be just way too cool. Thanks;
