VoIP/GSM Routing

VoIP/GSM routing precedes Least Cost Routing (LCR) and can be used to specify an order for
exchange line assignment to certain prefixes or complete phone numbers. The LCR provider
will then be dialled in advance at the selected exchange lines (except for GSM gateways). A
table with exception numbers must be set up for this and saved in the PBX.

VoIP/GSM Routing Sequence

VoIP/GSM routing proceeds as follows:
• A user dials an external number.
• The PBX checks whether the phone number or the phone number range is specified in the
exception numbers and switched on for the current configuration.
• If the phone number is found, the PBX automatically forwards the dial attempt to the first
selected connection.
• If the selected connection is busy when dialled, the next connection selected is attempted
(up to three are possible).
• After a dial attempt with the third connection, if no connection is established, you hear the
busy signal.
Note:
If a call is initiated over a targeted exchange line access point or VoIP access
point, VoIP/GSM routing is not performed.
The VoIP/GSM routing is performed depending on the destination number, if
the exchange line settings (subscriber, group) do not prevent this (e.g.
exchange line authorisation only for selected connections, preferred
exchange line, call restrictor).
The PBX uses fixed network connections to handle emergency calls as a
priority (i.e. calls made to the phone numbers specified in Public switched
tel. networks > Emergency calls as well as the automatic alarm calls made
by the PBX.
The special numbers provided by the VoIP provider, for checking one's
account status or mailbox, for example, usually do not include a local code.
It is not possible to route numbers via the exception table. In order to correctly
dial these phone numbers, use targeted exchange line assignment with the
