different connections

We use the cisco 800 series routers for outside users, i have been told that if the user's ISP is using DSL the can not use the router with the cisco IP phone, only cable works is this true also is it true for satellite as well?

Re: different connections

Hi,

the cisco phone works fine over any media, including adsl, cable and satellite.

If you have cisco routers at the remote locations you will need not to worry about anything as it supports NAT for any SCCP protocol that is generally used for phones.

Hope this helps, please rate post if it does!

Re: different connections

Hello,

Do you use CCM or CCME? In either case, do these devices have an interface exposed to the internet to use as TFTP ?

Or, do you use VPN with the 800 routers ?
