I have be asked for some X calls to be Forced on net to Some Y numbers

where we need to do this change on CUCM or VGW...

Hi Sameer,

It is explained in detail in the following doc

Gateways and Trunks

You can configure gateways and trunks as OnNet (internal) or OffNet (external) by using Gateway Configuration or Trunk Configuration or by setting a clusterwide service parameter. When the feature is used in conjunction with the clusterwide service parameter Block OffNet to OffNet Transfer, the configuration determines whether calls can transfer over a gateway or trunk.

You can configure the following devices as internal and external to Cisco Unified Communications Manager:

•H.323 gateway

•MGCP FXO trunk

•MGCP T1/E1 trunk

•Intercluster trunk

•SIP trunk

Route Patterns

To classify a call as OnNet or OffNet, administrators can set the Call Classification field to OnNet or OffNet, respectively, on the Route Pattern Configuration window. Administrators can override the route pattern setting and use the trunk or gateway setting by checking the Allow Device Override check box on the Route Pattern Configuration window.

Hi Manish,

What is the use of this....i mean i Dial a number X & that to be transfer on Y then ...what is benefit of configuring Forced translation call

[Jonathan Schulenberg]

Forced on-net is a design concept that ensures calls from your internal users to your own TNs do not route out to the PSTN, which would be a waste of money and trunk capacity.

User A = 14045551000

User B = 14045552000

User A calls 914045552000 instead of just extension 2000.

Forced on-net is typically configured as translation patterns that match the possible off-net patterns a user might dial for the TN ranges you own. The DDI on those translation patterns modifies the dialed number to a format that will match the on-net DN.

This is a simplified explanation. A proper E.164 dial plan design can incorporate forced on-net at a more fundamental level, negating the need for the extra translation patterns for each TN block.
