Hi all,
I have CCME and NM-4B-U network module in it.
Cisco.com recommends connect a BRI U port with straight-through cabel...and I did that. NT1 led lights green. That's ok....
Layer1 and Layer2 are OK.
===========
CCME_2811(config-if)#do sh isdn st
Global ISDN Switchtype = basic-net3
ISDN BRI1/0 interface
dsl 16, interface ISDN Switchtype = basic-net3
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 16 CCBs = 0
The Free Channel Mask: 0x80000003
===========
CCME_2811(config-if)#do sh controlle bri 1/0
BRI slot 1 interface 0 with integrated NT1
Layer 1 is ACTIVATED. (ISDN L1 State F7, Internal State F7)
===========
If a call places from the telco-network, "user unavailable" message registered.....
"debug isdn q931" output:

What wrong with "BEARER CAPABILITIES" and how could I fix this trouble???
Maybe any other trouble exists but I can't see it :)
Solved! Go to Solution.

The NM-4B-U does not supports voice. You must use exclusively VIC2-2BRI-S/T.

It sounds like your B channels are busied out? Can you upload your config? Also a show voice port summary?
04-22-2009 07:08 PM
Sure I Can...In attachments....

Maybe p.bevilacqua is right? It's strange, but I does't see any VOICE-PORTs for BRI in router configuration.
However I can set "isdn incoming-voice voice/data/modem" in BRI-interface configuration. What is this stand for?
