Now we just need to configure a simple dialplan to handle our incoming calls and to
send calls via the service provider. We’re going to modify the simple dialplan we started
building in the “Setting Up the Dialplan for Some Test Calls” section of this chapter.
The italicized sections are the new parts that we’re adding to the dialplan, with every-
thing else existing previously. †

Connecting Two Asterisk Boxes Together via SIP

There may come a time when you have a pair of Asterisk boxes, and you’d like to pass
calls between them. Luckily this isn’t very difficult, although it does have some oddities
that we need to deal with, but from the configuration viewpoint it isn’t really all that
difficult.

† We also assume you have configured at least one SIP extension from the previous section.
