System Functions and Features as of I7.9
144 Call routing
syd-0200/3.0 – I7.9 – 11.2009
5. 3. 1. 1 Call from the Public Network
A call with a suitable direct dial number is routed to the destination via the call dis-
tribution element allocated in the direct dialling plan.
If a suitable direct dial number is not found, the call is routed in the same way as a
call from the public network without direct dialling (see "Routing without Direct Di-
alling", page 145).
Direct dialling is not supported for calls from the analogue network.
