/mcpExample string value in the User-Agent and Server header Value specified for SIP profile parameter "Version in User Agent and Server Header" Cisco-CUCM10.0.1.98000-19 Full Build Header will be omitted None The value “Major and Minor” matches the current behavior and is the default value. CTI Video You can advertise video capabilities of SIP endpoints to CTI applications after successful registration. When the video capabilities of the endpoints are known, CTI applications can take into account the video capability of the calling and called endpoint during call routing. Unified Communications Manager will also notify the CTI application with the setup and tear-down of video streams during a call session. To support this feature, SIP video endpoints are required to report additional feature tags to indicate video capabilities in the SIP REGISTER message. When the endpoint refreshes its registration, it must continue to include these feature tags - to keep these capabilities active in Unified Communications Manager and CTI application. Absence of these tags in a subsequent registration implies this capability is no longer available. The following table indicates the fields that endpoints should send in the Contact header of a SIP REGISTER message. Comment SIP REGISTER Contact Header Parameter Name Capability Defined in RFC 3840 If "video" parameter is present in Contact header, it indicates that the device is video capable. The absence of this parameter indicates that the video is not enabled on the device or device is not video capable. video Video capable If this parameter is not present, Unified Communications Manager will report unknown. x-cisco-multiple-screen=<n> where <n> is number of screens. Number of screen Presence indicates support for Telepresence Interoperability Protocol (TIP). Absence of this tag implies that the device does not support TIP. x-cisco-tip Tele-presence Interoperability Examples of Contact in SIP REGISTER Device is video capable. TIP is not supported. Number of screen is reported as unknown.
