Route Patterns
There are 3 default route patterns that are built in to the sip server.
These are viewable in the administrative portal.
The first is 10 digit dialing.
XXXXXXXXXX -> default gateway
example: 2178751234
The second is 11 digit dialing.
XXXXXXXXXXX -> default gateway
example: 13098261234
The third is to route 911 call outbound to a PSAP.
911 -> default gateway
The default gateway IP is configured in the global SIP server configuration.
NOTE:
All three route patterns are checked at the same time of each route check and independently of the SIP registrar.
