I was wondering when I was going to see you ask this question. &nbsp;Have you thought about using IP unnumbered so that the serial side doesn't use IP addresses of it's own and instead just uses the Ethernet interface (or any interface you specify) as the source IP address?

My proble is that I have the ethernet as a Public IP an the serial link as a private 172.X&gt;X.X, so when a call originates from the router it has the return address of 172 which is not public. &nbsp;Any wy I can resolve this without changing the private subnet to a piblic one?<br />

Using a 3600 as a VoIP GW and a IP GW

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
