Mobile Voice Access
- MVA allows users to call into the enterprise from any phone and place outgoing calls that appear to come from their office phone
- Originate enterprise calls from any remote destination by:
- Dialing to the enterprise MVA number
- Entering ID (if required) and PIN
- Entering destination number to be called
- Called party sees the office phone number as the calling party
- Switch active calls between office and remote phone
Requirements
- H.323 or SIP gateway providing Mobile Voice Access IVR application
- Out-of-band DTMF
- Remote destination must be external devices
CSS
- When calling into MVA, the CSS on the line and the CSS on the Remote Destination Profile are combined to determine the effective user CSS.
- New in CUCMv7, there is a new CUCM service paraemter that determines the CSS for MVA calls: Inbound CSS for Remote Destination
- This can be set to the trunk or gateway inbound CSS (Default)
- Or the Remote Destination Profile + Line CSS (same behaviour in CUCMv6 handling).
