Chapter 23 Configuring Your Cisco IOS Gateway for T.37 On-Ramp and Off-Ramp Fax Support
Configuring Your Cisco IOS Gateway for T.37 On-Ramp and Off-Ramp Fax Support
Configuring the Fax Gateway for the Fax Detection Application
Prerequisites
You must configure at least one of each of the following dial peers on the on-ramp gateway:
• Inbound POTS dial peer
• VoIP dial peer
• MMoIP dial peer
The following sections explain how to configure each of these dial peers.
Inbound POTS Dial Peer
When you configure an inbound POTS dial peer on the on-ramp gateway, the incoming called-number
string specifies a pattern that represents either the prefix or the full E.164 telephone number (depending
on your dial plan) that identifies the destination voice mail telephone number for this dial peer.
The following example shows a configuration for an inbound POTS dial peer on the on-ramp gateway:
se-10-0-0-0 (config)# dial-peer voice 1 pots
se-10-0-0-0 (config-dial-peer)# application fax_detect
se-10-0-0-0 (config-dial-peer)# incoming called-number 75..
se-10-0-0-0 (config-dial-peer)# direct-inward-dial
se-10-0-0-0 (config-dial-peer)# exit
VoIP Dial Peer
You must configure at least one outbound VoIP dial peer on the on-ramp gateway for voice messaging.
In the example below, the IP address of the voice mail server is 172.16.2.2. If you have already
configured an outgoing VoIP dial peer on this gateway with the appropriate destination pattern, you do
not need to configure another one; there are no different dial-peer parameters for fax detection on the
outbound VoIP dial peer for voice.
The following example shows a configuration for an outbound VOIP dial peer on the on-ramp gateway:
se-10-0-0-0 (config)# dial-peer voice 2 voip
se-10-0-0-0 (config-dial-peer)# destination-pattern 75..
se-10-0-0-0 (config-dial-peer)# session target ipv4:172.16.2.2
se-10-0-0-0 (config-dial-peer)# dtmf-relay h245-signal
se-10-0-0-0 (config-dial-peer)# fax rate disable
se-10-0-0-0 (config-dial-peer)# exit
MMoIP Dial Peer
You must configure at least one outbound MMoIP dial peer on the on-ramp gateway. In the following
example, the session target command specifies an address to which faxes are e-mailed, where the $d$
wildcard is replaced by the destination pattern.
The following example shows a configuration for an outbound MMoIP dial peer on the on-ramp
gateway:
se-10-0-0-0 (config)# dial-peer voice 7 mmoip
se-10-0-0-0 (config-dial-peer)# application fax_on_vfc_onramp_app out-bound
se-10-0-0-0 (config-dial-peer)# destination-pattern 75..
se-10-0-0-0 (config-dial-peer)# information-type fax
se-10-0-0-0 (config-dial-peer)# session target mailto:$d$@mail-server.com
se-10-0-0-0 (config-dial-peer)# exit
