Techniques for providing for a seamless call transfer in a virtual desktop environment are supported. An apparatus may be capable of requesting access to a remote computer system for registration with a call manager, determining whether a call associated with the apparatus is active, automatically initiating suspension of the call in response to determining that the call is active and requesting registration of a telephone associated with the call, and resuming the suspended call. The seamless call transfer system may result in a more favorable calling experience during authentication with a virtual desktop environment and registration with a call manager.
