Hello,

i have the following scenario:

1- one gateway (PRI Line interface)

2- two RightFax servers


i used a SIP protocol between the gateway and the two fax servers , my point is how to configure a dial-peers on a gateway to make an inbound balancing fax call between the two fax server, the following is the configuration for the gateway:



### connection to the Fax Server #####

dial-peer voice 200 voip

destination-pattern 9979..

voice-class codec 99

session protocol sipv2

session target ipv4:10.72.28.110

session transport udp

dtmf-relay h245-signal

fax rate 14400

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none

!

#### Connection to the server Fax2 ####

dial-peer voice 201 voip

destination-pattern 9979..

voice-class codec 99

session protocol sipv2

session target ipv4:10.72.28.111

session transport udp

dtmf-relay h245-signal

fax rate 14400

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none

That's all you need.


You can use "show dialplan number " to see what dial peers will be used.

It will try, and when it is unreachable, it will attempt to send to it.


You may want to look into Out of Dialog (OOD) options pings. This will allow you to monitor the health of a SIP endpoint and fall-back when something fails.



thanks,
