Outbound Route Configuration - Asterisk

Route Configuration:

Create a Route name SIPUS_xxxxxxxxxx where xxxxxxxxxx is your SIP.US trunk.

We recommend adding the following 5 Dial Patterns(SIP.US requires 1+10 digit dialing within NANPA  and N11/N33 for Emergency and Directory Services and no prefix for International dialing(only country code + number)):

Example of Outbound route Dial Pattern in FreePBX gui:

Prepend  + Prefix  | Match Pattern

                                1NXXNXXXXXX

                                N11

                                N33

1                              NXXNXXXXXX

                 011         .

Set the Trunk Sequence for Matched Routes:

xxxxxxxxxxGW1

xxxxxxxxxxGW2

Note: The 011 prefix for international calling in the above dial pattern example will be stripped by the pbx before sending.
