Outbound call routing 29-6
Chapter 29: Understanding Wave Call Routing
Wave Global Administrator Guide
If Wave sees a number (following the external digit) beginning with a number other than a 1, it
is identified as a local (7-digit or 10-digit) number. (If the local area codes for 10-digit dialing
are included in the First Digit Table, then there is no need to dial a one to send calls to numbers
in those area codes.)
If Wave sees a number beginning with a 1, it expects to collect 10 more digits before routing the
call. If the number begins with 011, Wave expects a variable number of digits, and will route the
call after the dialing time-out expires (or the user presses #).
Access profiles
Access profiles control the types of outbound calls that can be placed from different sources in
Wave, such as specific phones and trunks or channels. Using access profiles, calls can be routed
or blocked based on rules you specify. Access profiles assigned to specific call sources can be
overridden in the global access profile Special Digits Table and area code table.
For example, if a phone is assigned an access profile that limits calls made from that phone to
internal extension numbers, and a user dials a number beginning with an external digit, such as
9, the call will be blocked (and the user will hear a fast-busy tone). However, if the Special
Digits Table in the global access profile allows the number 911 to be routed to a trunk group, a
call to 911 from the restricted phone will be routed.
Outbound routing tables
Outbound routing tables are reusable, prioritized lists of outbound trunk groups (and IP
telephony Signaling Control Points), and associated digit translation rules.
The routing tables allow you to set up outbound routing scenarios such as least cost routing,
where Wave will first attempt to place a call over the cheaper trunk group. If the routing scenario
fails, (because all the channels in that trunk group are in use, disabled, or disconnected,) the
PBX attempts to place the call over the next trunk group specified in the next step in the routing
table, and so on. (This is illustrated as My Out Route in the next diagram.)
An outbound routing table also allows you to translate the dialed number in a different way for
each trunk group. For example, some trunks may require long distance numbers to be 10 digits,
some 11 digits.
