[cisco-voip] First ring on inbound call to H323 Gateway

[Brian Schultz]

I just changed a 2821 voice gateway from MGCP to H.323 with CUCM 6.1.  After
the conversion, all inbound and outbound calls work fine.  The
only noticeable difference is that the inbound caller does not hear ringback
on the first ring.  So if the IP Phone user answers the call on the first
ring, the inbound PSTN caller just hears the user answer and doesn't hear
ringback.  Not the end of the world, but I'm wondering if there is a
dial-peer or voice-port setting to adjust this behavior?

2821 is running 12.4(15)T7 with PRI connection to PSTN.  Standard pots and
voip dialpeers:

dial-peer voice 1 pots
 incoming called-number [0-8]...
 direct-inward-dial
 port 0/0/0:23
!
dial-peer voice 1000 voip
 destination-pattern [0-8]...
 voice-class h323 1
 session target ipv4:10.128.110.11
 dtmf-relay h245-alphanumeric
 codec g711alaw
 no vad


Any ideas?

Thanks,
Brian
