cisco pbx

Unanswered Question

Hi,

How does the connection between a cisco call manager and the cisco pbx works and how does the cisco phone central work in general?

can already existing pstn and isdn lines be connected to a call manager?

the reason why i'm asking this question is because I am wondering how a local network with a few ip phones and a callmanager gets connnected to "the world" how phonecalls with regular phones can be received and made.

anyone who can give me some more info on this topic?

thanks in advance

I have this problem too.

exactly what do you mean when you say "cisco pbx"???

you use a gateway using H323, MGCP to control a T1/E1/FXO connection or a sip trunk to communicate to the PSTN
