6. 3. 1. 1 Call from the Public Network
A call with a suitable direct dial number is routed to the destination via the call distribu-
tion 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 Dialling",
page 171).
Direct dialling is not supported for calls from the analogue network.
