Call Routing

5.2.1.1
Call from the Public Network
A call with a suitable direct dial number is routed to the destination via the call
distribution 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 Page 2.120).
Direct dialling is not supported for calls from the analogue network.
