CUCM doesn't handle this type of configuration well. (CUCM Can't handle fractional ISDN-30s)
If these channels are just for incoming calls, and you don't need to strip different ammounts of digits at the gateway for each group, then you should be able to lie to CUCM and tell it that it's a got a normal 30-channel ISDN-30.
Of course, the best solution, would be to get the DASS-2 converted to Q.931 and get the two DDI ranges sent over all 30 channels. DASS-2/DPNSS<>Q931/QSIG convertors are "OK" but can give headaches. Plan to get rid of them ASAP.
PS I didn't think DASS-2 was still a supported service from BT.
Just an update to this thread. The DASS2 converters are installed and working well. The supplier was able to configure them so that calls to the channel groups on the DASS2 side are just presented on ascending channels on the Cisco gateway side.
All pretty painless! - link below to the converter webpage for anyone who comes across a similar requirement.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
