I have Tandberg H.323 endpoints registered in gatekeeper, Callmanager 4.2(1) and MGCP voice gateway to classic telephony. There is a problem, when I try to set up a call from H.323 endpoint to the analog phone through voice gateway. The call is set up but disconnets after about 3 seconds alerting signal. However you can have normal connection, when you answer the phone during theese three seconds of alerting. When it disconnects it says: 'Resource unavailable, unsecified'.
