I want to connect KX-TD with a Cisco router with Call manager express via kx td 280. I can acces from Cisco IP Phone to Panasonic Extension but NOT the other way: I can't call from Panasonic extension to Cisco (ISDN ports connected as ext or CO - no difference). Can somebody help me?

I'm guessing that the 280 card is European.
we have a TD180 CO card ant a TD290 PRI card but no 280 card.
sorry, can't help ya.

My problem is that I can see that the call I make from Cisco is comming through CO 11 but I cannot access CO11, It doesn't exist. Is there something else I should validate?

280 is 2 port ISDN BRI S0

I e mailed you all the installation and programming Tech. tips I have on ISDN here
in the US.
I'm sure the programming is similar.
I hope this helps you out.

Ciprian, are you sure that the MSN numbers Cisco programmed correct. Also check that the cisco accept speech / 3.1 KHz audio calls.

I don't know how MSN works. My ISDN ports are connected as CO to Cisco router.When I call from Cisco to PBX the call is routed as MSN table or when I call from PBX to Cisco? I think first is the right situation. So, if I set for CO 9 the number 12345 recordings from MSN table should begin with 12345,right?
