Phone number with an exchange access prefix
If the phone number has an exchange access prefix without route information (Ex-
change access business, Exchange access private, Cost centre selection), the call will
be routed on via the transit route.
If the phone number has a route selection prefix, the call will be routed via the corre-
sponding route.
Note:
If a number has a route selection prefix and if numbering plan identifier (NPI) is E.164, the call
will be routed via the transit route without truncating the prefix.
The exchange access prefix is set under Send access code in the route configuration
of the source PINX.
