Call Transformation

[mightyking]

Hi,

Our outgoing calls are in +1XXX-XXX-XXXX format. We need to remove the "1" before sending the call to Telco.   I know this can be easily done using translation rules in the GWs but the restriction is that this needs to be done in the CUCM. How can we accomplish this using callmanager. Please note that the phones and trunk to the GW are SIP.. There're FXO ports going to PSTN.

Thanks,

MK

are you using h323, SIP or MGCP gateways from a Call Managers perspective?

either way, if you are using standard local route lists, 

  go into your Route List Detail Configuration

and under calling party transform mask set XXXXXXXXXX

Thanks Dennis,

That will change the behaviour for all LRGs. We have more 100 sites which work with no issue. There're only 3 sites where telco doesn't want the digit 1.

The phones and the trunk to the GW are SIP.

Thanks,

IN that case,  I think you have given the answer yourself,  

go to the relevant gateway and under Call Routing Information - Outbound Calls

set your Called Party Transformation CSS  and make sure the CSS contains a transformation that strips the 1 off.

apply that same Css to your 3 gateways

This is already done and the 1 is still being sent. Please see the above DNA output.

Please share your called party transformation rule and the CSS configuration. Also, are you using "use device pool CSS" or "assign CSS to SIP trunk".

Is this complete DNA? I don't see route pattern and route list sections.

Hi,

Here's the required info.

Thanks,

Your called transformation looks correct. However, your DNA isn't showing the matched router pattern. I need to see the entire DNA to see which route pattern is matched.

My feeling that your aren't matching the right route pattern and not going through the right trunk where the called transformation pattern CSS is applied.

MK,

 take a look at the following:

...
Called Party Transformations
 Called Party Mask =
 Discard Digits Instruction = PreAt
 Prefix = +1
 Called Number = +15068591990
...

Although you use a PreAt you are also using a Prefix of +1, in other words, 9@5068591990 become +15068591990.

Double check your configuration, and look for the Prefix = +1 and remove it.

Hope this helps.

Thanks Guys,

The problem was a combination of what Mohammed and Marcelo mentioned.

Thanks to both of you,

Hi MK,
 you are welcome.

 Remember to mark both answers as correct, it's a useful info for future research.

Best Regards.

Whats your Gateway H323/MGCP? Are you using specific route patterns or the IDP dial plan?

You can just use Route-Pattern/RL-Details, Called Party transformation and use discard pre-dot, if your environment allows.
