hi, interesting problem here:
sometimes when dialing out from an ip phone I don't hear a ringback from the called number - sometimes I do. This has no pattern as to numbers etc, it just happened intermittently.
I am on a 2821 ios 12.4 spservices. h323 with local break out over PRI isdn.
my dial peer config for pots is:
dial-peer voice 1 pots
tone ringback alert-no-PI
description *** Outgoing calls to PSTN ***
progress_ind setup enable 3
progress_ind alert enable 8
progress_ind progress enable 8
progress_ind connect enable 8
translate-outgoing calling 2000
incoming called-number .
any help is resolving this would be appreciated.
