Hi all,
Does anybody faced ringback issues with CCM 3.2(2c) and a 2600/E1 gateway ?
When an IP-Phone calls a phone connected to a PBX behind the E1 gateway, I do not hear ringback in the IP-phone.
I tried the progress_ind commands in the h323 dial-peers.
Aso the voice rtp send-receive and the voice call send-alert commands.
And MGCP on the router did not resolve my problem...
I'm running 12.2(11T)
Is it a bug ? on CCM ? on the router ? any workaround ?
Thanks for your feedback.
Cheers,

this is what we have on our dial peers for extensions on a pbx
dial-peer voice 4 pots
destination-pattern 6...
direct-inward-dial
port 1/0:15
forward-digits all
and this is what we have for pstn access through our pbx
dial-peer voice 2 pots
destination-pattern 9T
progress_ind alert enable 8
progress_ind progress enable 8
progress_ind connect enable 8
direct-inward-dial
port 1/0:15
forward-digits all
this is through an h323 gateway, though we are on a lower version of ios 12.1(5)T8
hope this helps

We had the same problem with CCM 3.2 (2a) and a VG200/T1 gateway. We wnet back and compared the programming that we had on the 2600 that we had borrowed from Cisco. We fixed the problem by adding adding lines under MGCP (we are running 12.2(11T). The VG200 now looks like this:
mgcp
mgcp call-agent ALEX 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
mgcp rtp unreachable timeout 1000 action notify
mgcp package-capability rtp-package
mgcp package-capability sst-package
mgcp default-package dtmf-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp fax t38 inhibit
mgcp rtp payload-type g726r16 static
!
mgcp profile default
Good luck.

We have the same MGCP config but still have the problem. Any suggestions?
