Hello all.
I've this annoying problem.
I've a 3640 router configured as RAS, with an ISDN PRI lines and 18 mica-modems.
All work properly.
Now I need to migrate RAS on a BRI, so I've installed a WIC-1BRI on ther router and configured it to answer my calls.
But it doesn't work.
When I call BRI line, I heard a fast busy signal, and router log this error:
5w0d: ISDN BR1/0 **ERROR**: accept_incoming_csm_call: modem problem Requested circuit/channel not available(0x2C): b channel 0, call id 0x95
5w0d: ISDN BR1/0 **ERROR**: host_disconnect_ack: VOICE ERROR: Invalid CSM info(0xFB): b channel 0, call id 0x95
I've tried with two different lines from two different ISP, but problem is the same.
Any suggestion will be appreciated.
Thanks
Daniele

You must use a BRI Network Module, not WIC. Check:

Sorry for my inaccuracy, obviously I've installed the wic into a NM-2M module.
if I had not done this router didn't recognize wic (and I don't have a place where to insert it).
extract from show version:

What I'm trying to tell you, you need an NM-4BRI, or NM-8BRI, as specified in the document, WIC are not supported.
