Hola,

do you ave configured clocks correctly ?

network-clock-participate wic 0

network-clock-select bri 0/0 1

also please try:

int bri 0/0

isdn tei-negotiation preserve.

If still issues please send output of "debug isdn q921" takeb with "term mon".

hope this helps, please rate post if it does!

Hi,

the switch is bringing down L2, but strngely not L1 as well. You can try making and receiving calls anyway.

I would report it as incorrectly activated due to the reason above.

alfbrt2133 Sat, 11/17/2007 - 02:33

but,

i can't do any call.

no incoming and outcoming call's work.

Thanks

Alfonso

this "voice-port 0/0/1no caller-id enable" is a problem ???

why ??

regards again.

Alfonso

Paolo Bevilacqua Sat, 11/17/2007 - 07:12

No sure, but it seems a bug in CM.

It tries to configure two commands on a single line, beside "caller-id" is not an option for BRI.

alfbrt2133 Sat, 11/17/2007 - 07:16

thanks for all.

i write two new post about this problem.

i think the problem is not call manager...

if you can read the other 2 post and answer me....

thank you very much.
