Communication Manager supports channel type identification over ASAI to a CTI application from 7.1.1 onwards. For incoming SIP trunk calls, Communication Manager Release 7.1.1 and later identifies the channel type as voice, video, or unknown when the call:
Enters a monitored Vector Directory Number (VDN) or hunt group (skill/split)
Is monitored and is alerting at a deskphone or Agent
For this feature to work, the CTI link between Communication Manager and Application Enablement Services must be greater than 11.
This feature might not work or might show an unknown channel type on the CTI application when:
The Direct Media feature is enabled
Communication Manager is not able to identify the channel from the incoming SIP request
