Voice translation profiles match called number then manipulate calling numb

[aekstrom]

Hi There,

I'm using Cisco 2821 GW With H323 on the voip side and ISDN E1 to PSTN.

I would like to hide or change the calling number when dialing a specific prefix to PSTN. This is for users who do not want to show there extension number out to PSTN.

I can not see how to match a called number and manipulate the calling number?

Does anyone have a solution for this on the gateway?

Best Regards

i did't understand where You must act(call manager or gateway)

[aekstrom]

In this solution we are using a 3rd party IP-Pbx.

I would like to do this in the gateway with translation-rules but I can not see how to do it.

Regards

Andreas,

When we've done this in the past, we've had the users dial *67 as a prefix to the number to invoke this feature. So you could do something like this...

voice translation-rule 1

rule 1 /.*/ //

!

voice translation-profile BlockCLID

translate calling 1

!

dial-peer voice 100 pots

destination-pattern 9*67[2-9]......

port 0/0/0:23

direct-inward-dial

translation-profile outgoing BlockCLID

Also...if you have a CallManager involved, this becomes a lot easier and the gateway config is not necessary. From your description, however, I'm inferring that you have a gateway only solution.

Hope this helps!

In your example you have a dedicated PSTN connection for blocking CLID and match on the destination-pattern in that dial-peer and then remove the CLID with a translation-profile.

In my case we are using this dial-peer for all external calls and would like to show the CLID for all calls except the ones dialing this special prefix to hide it. I can not see how to separate the calls in the same dial-peer.

Thanks

You can act on the inbound dial-peer using answer-address [calling number] and then manipulate these calls!

Here are my voip dial-peer.

dial-peer voice 200 voip

destination-pattern ....

voice-class codec 1

voice-class h323 1

session target ipv4:x.x.x.x

incoming called-number 0T

dtmf-relay h245-alphanumeric

no vad

So could i create another dial-peer without a destination-pattern to the same IP? and specify in incoming called-number my prefix to hide the CLID?

Something like this?

dial-peer voice 201 voip

translation-profile outgoing noCLID

voice-class codec 1

voice-class h323 1

session target ipv4:x.x.x.x

incoming called-number 9983T

dtmf-relay h245-alphanumeric

no vad

voice translation-rule 5

rule 1 /.../ /0000/ plan any private

voice translation-profile noCLID

translate calling 5

So in this case will the router check the called number from the same IP for 0T or 9983T and then send that call through the right dial-peer?

Anyway I will do some testing on this.

Thanks

Edit your Post and omit the IP addresses as they are public IPs.

[alessandro.dona · Accepted solution]

When you dial 9983 inbound dialpeer 201 should be matched ,Then translation applied

and outbound dialpeer matched!

It could work out!

Let me know if it does !

[aekstrom]

Yes it works. :)

With "debug voice dialpeer" I can see that incoming dial-peer 201 is matched with prefix 9983 and dial-peer 200 for others numbers..
