Cisco Cisco Unified Customer Voice Portal 11.0(1)

The following are reasons why new customers may need to use H.323 for call control:

•

Cisco PGW media gateway controller (MGC) in call control mode is used to initiate calls to
Unified CVP

•

GKTMP NIC is used for pre-routing

•

Hook-flash is used to transfer calls

Queue and Transfer Model

This model, which was supported in previous versions of CVP, is not supported for new
customers in Unified Customer Voice Portal 4.0. New customers are advised to use the
Comprehensive model instead.

However, existing customer who are upgrading to Unified CVP 4.0 while continuing to use
ICM 6.0 or earlier, do not always have this option. Such customers who:

•

Do have IP-originated calls, must stay with H.323 and continue terminating media on the
H.323 Service (formerly called the CVP Voice Browser)

•

Do not have IP-originated calls, are encouraged to move to SIP; they may choose to stay
with H.323, but in that case they must remove media termination from the H.323
Service—since, within the Unified CVP solution, Gateways and Unified CallManager devices
are the only components that terminate voice
