Routing with Direct Dialling
A call with a suitable number in the direct dialling plan is routed to the destination
via the call distribution element allocated there.
If the first few digits of the phone number match the number entered under Own
regional prefix in the numbering plan, they will be truncated before the search for a
suitable direct dial number is carried out.
