When a Cisco device is handling both modem and voice calls, it needs
to be able to identify the service type of the call--meaning whether the
incoming call to the server is a modem or a voice call. When the access server
handles only modem calls, the service type identification is handled through
modem pools. Modem pools associate calls with modem resources based on the
dialed number identification service (DNIS). In a mixed environment, in which
the server receives both modem and voice calls, you need to identify the
service type of a call by using this command.
If you do not use this command, the server attempts to resolve
whether an incoming call is a modem or voice call on the basis of the interface
over which the call arrives. If the call comes in over an interface associated
with a modem pool, the call is assumed to be a modem call; if a call comes in
over a voice port associated with a dial peer, the call is assumed to be a
By default, there is no called number associated with the dial peer,
which means that incoming calls are associated with dial peers by matching
calling number with answer address, call number with destination pattern, or
calling interface with configured interface.
Use this command to define the destination telephone number for a
particular dial peer. For the on-ramp POTS dial peer, this telephone number is
the DNIS number of the incoming fax call. For the off-ramp MMoIP dial peer,
this telephone number is the telephone number of the destination fax machine.
This command applies to both VoIP and POTS dial peers and to on-ramp
and off-ramp store-and-forward fax functions.
This command is also used to provide a matching VoIP dial peer on the
basis of called number when fax or modem pass-through with named signaling
events (NSEs) is defined globally on a terminating gateway.
You can ensure that all calls will match at least one dial peer by
using the following commands:
Router(config)# dial-peer voice tag voip
Router(config-dial-peer)# incoming called-number.
The following example configures calls that come into the router with
a called number of 555-0163 as being voice calls:
dial peer voice 10 pots
incoming called-number 5550163
The following example sets the number (310) 555-0142 as the incoming
called number for MMoIP dial peer 10:
dial-peer voice 10 mmoip
incoming called-number 3105550142
