PSTN to IP Phone!?!?

Hi,

We just implement VoIP by using Callmanager, we have no problem to call IP Phone to IP Phone.

However, what stuff i need to call from IP Phone to PSTN or PSTN to call IP Phone???

Thank you very much.

You need a "gateway." Please see the following document to help you choose a gateway for your needs:

I have the same situation with kenneth. I would like to know where I could get details on how to configure Cisco 3660 with CallManager 3.0(7).

I have an IOS ver 12.1 IP Plus and FXO modules.

Kenneth,

Yep you need a gateway. You can either put a blade in a catalyst etc. or you could use a VG200 if you want something to stand alone. Hope that helps.
