One-Stage Dialing versus Two-Stage Dialing

The VoIP network configuration inter-works with the normal telephone network
or PABX of the office in most of cases, so multi-staged dialing is made. To
decrease dialing stages, users shall add the telephone number of the
termination side and the telephone number of the next stage to the called
party number when setting a call in the termination side.
Consider that a subscriber connected to the voice port of the Gateway A
attempts to make a call to the subscriber who is using PABX line #100 that is
connected to the other VoIP Gateway B.

Consider that the VoIP peer setup of the Gateway A is as follows:
dial-peer voice 555 VoIP
destination-pattern 310555....
In the above, as soon as the subscriber of Gateway A enters 3105551000, the
outbound VoIP peer 555 will be decided and a call will be connected to
Gateway B.
