Extension & Device Mobility for Cisco users in India

Hi ,

As you know this feature is mostly blocked in India because of the possibility that these features could bypass the PSTN when placing calls.

On web browsing, I could locate some case study (as attached) on allowing Extension Mobility for India Users thru Logical partitioning.

What I understand,

  • With Logical Partitioning we can use this feature.
  • When Employee logs in to the phone the Cisco UCM applies the user’s profile (which defines phone number, speed dials, & other features) to that phone.
  • On-net Calls will get routed in same manner
  • But there is still limitation with Off net calling . When employee is at another site CUCM cannot route off-net calls through their home gateway, it must use local gateway instead.
  • To solve this issue, Off-net calls from Extension Mobility are routed through a receptionist in order to help ensure correct PSTN routing.
  • When logged in from Home. With the Device Mobility , Cisco CUCM checks the IP address of the phone to identify its Cisco Office VPN Subnet. It will identify & allow On-net calls but block Off-net calls.

Do you see any further amendment in this

I am more concern on how we can allow PSTN calling through local gateway & not Home Gateway without intervention of a receptionist.

Appreciate your views on this & if it is implemented in anywhere in India.

Rgds, Reha
