receiving, at the server system, a telephone access request originating from the user operating the client device associated with the user logon;

determining a telephone number assigned to the user operating the client device;

retrieving, based on the telephone number, softphone configuration data from a telephony service, wherein a softphone is a virtual or physical end user telephony device, and wherein the softphone configuration data, in response to activation of a softphone associated with the client device by a user operating the client device, enables the softphone to register itself, and the telephone number, with the telephony service, wherein registering with the telephony service indicates to the telephony service that the smartphone is ready and authorized to consume telecommunications functions with respect to the telephone number including providing a data connection between the softphone and the telephony service to send and receive calls using the telephone number; and

transmitting the softphone configuration data to the client device,

wherein the server system is part of a cloud-based server platform configured to deliver the remote desktop for a cloud-based virtual machine to the user, and wherein the softphone configuration data is transmitted to the client device without transmitting the remote desktop together with the softphone configuration data to the user such that the client device provides telephone access independent of the remote desktop.

11. The non-transitory computer readable storage medium of claim 10 wherein determining the telephone number assigned to the user comprises: transmitting a query to a directory service configured to maintain predefined mappings between a plurality of users and a plurality of telephone numbers, the query including information identifying the user; and receiving the telephone number in response to the query.

12. The non-transitory computer readable storage medium of claim 10 wherein transmitting the softphone configuration data to the client device comprises: generating, based on the softphone configuration data, an encrypted softphone startup file; and transmitting the encrypted softphone startup file to the client device.

13. The non-transitory computer readable storage medium of claim 10 wherein the client device is configured to activate the softphone using the softphone configuration data, wherein the activating causes the softphone to register itself, and the phone number, with the telephony service, and wherein the registering allows the softphone to establish a data connection with the telephony service for sending and receiving telephone calls using the telephone number.

14. The non-transitory computer readable storage medium of claim 10 wherein the method further comprises: storing, in a database accessible to the server system, a copy of the softphone configuration data and a database entry identifying the user, the telephone number, and a file path of the stored copy; receiving a telephone access request from the user via another client device; retrieving, based on the database entry, the copy of the softphone configuration data from the database; and transmitting the copy of the softphone configuration data to said another client device.
