Internal call routing
Internal call routing refers to all calls that originate and terminate within Wave. Internal calls
can include calls such as station-to-station, station-to-hunt group, station-to-voicemail, and
station-to-Attendant hunt group.
The following diagram shows how a station-to-station internal call flow might look:
This diagram illustrates the following:
1 The user at extension 102 dials 1-0-1.
2 The first digit collected, 1, is specified in the First Digit Table as type Extension (and
requires 2 additional digits to be collected before routing the call).
3 Once a three digit number beginning with 1 is collected, the PBX looks for extension 101.
4 Extension 101 exists, so the PBX routes the call to extension 101.
5 If the call to extension 101 is forwarded (or transferred), it goes through another round of
call routing beginning with the First Digit Table. If extension 101 is a user (not a hunt
group), the call is routed according to extension 101's active routing list.
Outbound call routing
Outbound call routing refers to calls that originate within Wave and terminate outside Wave
(over a trunk connected to the Wave Server). These calls can include outbound calls from phone
extensions, modems, and FAX machines.
