  • I do have that


    callerid=”Satish Patel” <7623>
    accountcode=”Satish Patel”

  • Interesting thing is when i reload sip.conf i got MWI lamp working on polycom 501

    But its not working when anyone leave voicemail. Do you know its some timeout or polling setting in sip.conf ?

    Still my question is my my asterisk not sending NOTIFY message ? Do i need to subscribe my phone to asterisk ?

    Sorry it my typo error.

    Yes, I can see there are 10 voicemail

    root@campbx1:~# asterisk -rx ‘voicemail show users’ | grep -i 7623
    default 7623 Satish Patel 10

  • Thanks steve,

    But you know if i connect X-lite softphone my asterisk sending NOTIFY .

    But its not sending NOTIFY to polycom 501 phone ? Do you think i need to subscribe my phone to asterisk ?


  • X-Lite automatically SUBSCRIBEs for MWI indication. Polycom and snom
    do not do this by default, instead they assume that the REGISTER will
    automatically cause MWI notifications.

    chan_sip changed behaviour (by accident I suspect) somewhere between
    version 1.2 and 1.6, and the patch basically puts back what went
    missing. It is crude, but has not caused me any problems so far.
