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.
11-17-2007 02:33 AM
but,
i can't do any call.
no incoming and outcoming call's work.
Thanks
Alfonso

Just report faulty circuit then. It's behaving strangely and cannot be used.
Good luck!

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.
11-17-2007 07:16 AM
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.
