Call monitor for SIP phone on SRST

oprochazka

Level 1

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.

Thanks,

Thx, I know that UCXSI doesn't support SIP.

Is there any other way? For example by SIP Subscribe message?

I don't find other way, you can check JTAPI.

JTAPI

Thanks,

There is no JTAPI on CME/SRST.

We are using JTAPI for normal situation, when Cisco Phone has connectivity to CUCM in DC. When WAN link is down and connectivity to CUCM is broken, Phone is registered to local SRST gateway (CME in SRST) and customer need to application will be running in this situation.

Is there any way?
