Hi,
I am having a problem where i have a QSIG connection between a Cisco 3845 and a Nortel Option 11C PBX. This router is configured as H323 registered to a CallManager 4.2(3)
When I use an IP phone and dial to a nortel phone.
The nortel phone is ringing, but I do not hear the ringing on the IP phone. There is a message "Ring Out" on the IP phone.
When I do a debug isdn q931 on the router, this is what I see:
Router#

Hope someone can help on this.

You may want to try the following:

This may be that old chestnut "isdn progress indicators". Try
progress_ind alert enable 8
under the outbound dial peer.
You may also need
progress_ind setup enable 3
on the inbound dial peer if there are ringback problems the other way

The progress_ind solved the problem.

Thanks all!
