Mobile Connect with Incoming Calling Party National Number Prefix

[afgitdepartment]

Hello,

We currently utilize the service parameter "Incoming Calling Party National Number Prefix - MGCP" to prefix all inbound calls from the PSTN with "91"

We are implementing Mobile Connect on a number of employees. 

The issue we have is when a call comes in from the PSTN to a mobile connect phone, the outbound call leg to the mobile phone prefixes the original calling part with the "91" so the callerid on the mobile phone appears as "91651XXXXXXX"

here's the Q931 output from the gateway:

How can I get the outbound call leg to show the "Calling Part Number" without the prefixed 91?

Hi,

One suggestion I have on this is to use a different approcah to prefix the incoming calling party with the 91. Do not use the service parameters..I find it not so helpful. Rather use a translation pattern as described in the link below..Feel free to clarify if you dont understand anything

Thanks for the feedback on this. I think we will consider using the inbound translation pattern on the gateway vs a service parameter to give us more control at a granular level.

i did find a work around to this and its to create a new partition, CSS, Route List, Route Patterns, etc and on the Route List Member Information I specified the Calling Party Transform Mask to be XXXXXXXXXX which leaves just the 10 digits of the original calling party's number being sent in caller-id back to the PSTN and to the called party's mobile device.
