Thanks very much. &nbsp;Will investigate the NT kernal info further. &nbsp;CIsco do report that they work over terminal services, but it is difficult to find out how.

I am trying to configure Cisco IP Phones to run over terminal services, so that each client is assigned their own softphone when they log in. &nbsp;However, the softphone devices are recognized by Mac address and not IP address. &nbsp;I therefore need an individual Mac Address for each softphone/terminal services client.<br />
<br />
I realize that mac addresses are usually based on the network card, of which there are only two in the server. &nbsp;Is there a way to enter/assign additional Mac addresses in terminal services, or is there another work-around?

Can Terminal Server (Server 2003)  Issue Multiple Mac Address Leases?

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
