    Call monitor for SIP phone on SRST

    oprochazka

      Hi All,

       

        do anybody know, if there is chance to monitoring calls for SIP phone on SRST (CME in SRST mode) gateway?

       

      I need to receive information about ringing and connected call - calling and called numbers.

       

      I tried:

      - CME CTI - this API doesn't support SIP phones

      - subscribe for presence on CME - I receive only presence information that phone/line is busy - this information is without any calling/called numbers.

      - subscribe for dialog events - I receive OK confirmation, but next I don't receive any notify message from GW

      - subscribe for telephone-event - same as for dialog events

      - TCP and UDP version of SIP - same result

      - sending SUBSCRIBE request directly to the phone - the phone reject these requests - with response 489

       

      Thanks

      Ondrej
