Hi all,

Having some problems with a PABX integration for a customer. The Ericsson MD110 is a straight PRI connection with H323 dial peers (no QSIG) and from what I understand QSIG is not an option.

The system is setup like so:

ISDN --- H323 GW --- CUCM 8.0(2C)
            |
            |_____ Ericsson MD110



All inbound calls in a 200 number DID are routed to CUCM. There is a route pattern in CUCM to send unknown numbers back to the H323 gw with a steering code which then routes via POTS dialpeer to the PABX.

Calls from external to IP phones has ringback tone
Calls from external to PABX phones has ringback tone

Call from IP phones to PABX phones do not have any tone.



I've tried a number of different combinations of progress-ind alert, setup, progress, connect etc and "tone ringback alert-no-pi" as well as some of the CUCM service parameters such as:

Send H225 User Info Message  - Use ANN for Ringback

Check Progress Indicator Before Establishing Media - True


but no such luck...

Does anyone know what I might be able to do to achieve a ringback tone?

Thanks
Dana
