Call monitor for SIP phone on SRST

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

UCXSI API doesn't support SIP phones, only SCCP phones we can monitor.
