forward inbound call to external destination

I am struggling with something that sounds like it ought to be simple.

I have a 2901 UC voice gateway and need to redirect one of the inbound DDI numbers to an external destination. i.e. when you ring inbound from the PSTN to the number 123456 it should direct straight out to another PSTN number 654321 etc.

How should I achieve this, does it use translation rules or dial-peers or something else ?

Thanks

When you say you have UC 2901, is the router a CallManager Express system, or is it a voice gateway of off Communications Manager server? If you are unsure please post the configuration of the router.

HTH,

Hi Chris, It's just the voice gateway. no communication manager or any other cisco products involved.

Normally inbound calls from PSTN to the gateway are directed to a SIP PBX, but I need one destination number to just go straight back out to another PSTN number.

hope you can help

thanks

Here's one way of getting it done:

! Translate number on egress

voice translation-rule 1

rule 1 /^123456$/ /654321/

voice translation-profile 1

translate called 1

! Incoming POTS

dial-peer voice 1 pots

incoming called-number ......

direct-inward-dial

port 0/0/0:23

! Outgoing trombone of 123456 DID

dial-peer voice 2 pots

destination-pattern 123456

translation-profile called 1

port 0/0/0:23

! Toward CUCM

dial-peer voice 3 voip

destination-pattern ......

session protocol sipv2

session target ipv4:x.x.x.x

session transport udp

dtmf-relay rtp-nte sip-kpml

ip qos dscp cs3 signaling

codec g711ulaw

no vad

! Incoming VOIP dial-peer from CUCM note shown
