make a dialing plan, e.g.
if USER == number {
if user start with 0 {
#PSTN call
route to gateway
} else {
#IP call
lookup("location")
...
}
}

Just a quick question....I am using numerics as the
username (ex. 111000001)
of
my hosts. I am able to make pstn calls through my pstn gateway. My
question is how
do i configure the routing request lock to allow ip to ip calls between two
hosts. if i
dial 111000002 it routes the call to the pstn instead of to the other host.
here is my config so far.

# is it a PSTN destination? (is username nummerical and does not begin with
8?)
if (uri=~"^sip:[0-79][0-9]*@") { # ... forward to gateways then;
