Re: destination-pattern and incoming called-number

dial-peers are versatile in that they can function both as incoming or
outgoing.

One reason for that is that once you define an outgoing dp (a dp that is
mainly designed to be used as outgoing) for a given destination-pattern,
it duals as incoming dp for calls coming from the given pattern numbers.

But may be you need some other configuration for such incoming calls. In
that case, answer-address takes precedence with the same semantics
(calling number) and even more precedence is given to incoming
called-number, which matches called number.

A very good reason to use incoming called-number in a catch all dp is to
avoid the possibility of fraud, given that a dp with no cor list
is enabled to call everywhere...
