Translate Called Number to Another Before Sending to Next GW

Hello All,
Goal here is to send a call that is currently getting sent to CUCM where it then gets translated and routed accordingly, to have that number translated to another number before sending it along to the next Gateway instead.

The SIP Cube has a main inbound dial-peer that basically is a catch all to except the incoming call.

Currently on the SIP Cube/GW I created a translation-rule and profile:

!
voice translation-rule 206
 rule 1 /5551234567/ /2490/
!
!
voice translation-profile MAIN-FAX-INBOUND
 translate called 206
!

So I believe I now need an outbound dial-peer to direct the call to the next gateway in our network, where the fax machine is attached. And I was curious how the translation works. Does the translation rule/profile translate that number to 2490, and then send "2490" to the next Gateway? The next Gateway is expecting the number 2490.

Something like this?

!
dial-peer voice 2608 voip
 description Fax Machine - 555-123-4567
 translation-profile outgoing 800-FAX-INBOUND
 destination-pattern 5551234567
 session protocol sipv2
 session target ipv4: <fax-gw-ipaddr>
 dtmf-relay sip-kpml rtp-nte
 codec g711ulaw
 fax-relay ecm disable
 fax-relay sg3-to-g3
 fax rate 14400
 no vad
!

Wasn't sure if I was supposed to use incoming or outgoing for the translation-profile line in the dial-peer. Is it technically outgoing since its an outbound dial-peer to our next Gateway?

Any help would be greatly appreciated.

 

Thanks,

Matt

Thanks Vaijanath.

 

I ended up doing it slightly differently. It was a little bit more configuration. But, the result is the same. On the CUBE I configured a dial-peer to take the full fax telephone number, and just send that full number to the 2nd Gateway (*a 2821). On the 2821 I have a voip dial-peer with incoming called-number to accept the full number. Then, I have a few pots dial-peers using destination-pattern of the full number and the translation-profile to change the full number to 2490 and send the call out one of 4 pots lines all connected to a FaxFinder Gateway.

This configuration appears to be working as the Fax gateway/server is receiving faxes.

Re: Translate Called Number to Another Before Sending to Next GW

Hi,

You need below configuration:

Inbound Dial-Peer to match 5551234567 and translation profile to translate to 2490.

!
voice translation-rule 206
 rule 1 /5551234567/ /2490/
!
voice translation-profile MAIN-FAX-INBOUND
 translate called 206
!
dial-peer voice 9000 voip
 description ** INBOUND CALLS FROM SERVICE PROVIDER **
 translation-profile incoming MAIN-FAX-INBOUND
 incoming called-number 5551234567$
 ++++++ add other dial peer configuration parameters depending on your setup +++++++
!

Outgoing Dial-Peer to send the call to next gateway:

!
dial-peer voice 2608 voip
description Fax Machine - 555-123-4567
 destination-pattern 2490$
 session protocol sipv2
 session target ipv4: <fax-gw-ipaddr>
 dtmf-relay sip-kpml rtp-nte
 codec g711ulaw
 fax-relay ecm disable
 fax-relay sg3-to-g3
 fax rate 14400
