Cisco VoIP pri isdn problem

[bumbar]

Hello.
I have the following problem: I have Cisco AS 5350 and I connected PRI ISDN from Telco on its E1 port. Ir works fine concerning voice communication on B channel, but there is a problem with signalisation. When I try to call another ISDN number, I don't have call controll in my handset - I don't know if the other phone is ringing or is the line bussy. Seems to me that Cisco can't understand ISDN signalisation completly. When I call non ISDN number, I get the ringing signal, but don't get the bussy signal. Can I make Cisco to understand channel D signalisation?

Thanks.

Do you have a PRI or an E1? I don't think you can use a PRI in an E1 interface.


It is what it is!!
