Well, duh. Of course you do.
But what should be in that Quality of Service agreement? In a new report entitled Emerging Developments in Voice, Video and Data, consultants Frost & Sullivan say that enerprise VoIP QoS guarantees should adhere to a technical standard "which is on par or better than that is available over traditional telephony networks."
The QoS issue, the report surmises, is magnified by thefact that IP networks use statistical multiplexing rather than a dedicated end-to-end connection throughout the call.
"This method of using permutations and combinations in allocating the resources leads to optimal utilization of network resources at the cost of overall QoS offered to the end users," explains Frost & Sullivan analyst V.R. Yoges in a press release that accompanies the report's release.
Yoges added that toensure QoS, "vendors must pay close attention to delay, jitters, and the packet loss experienced in a network. In addition, transfer of calls between two networks must be without disruption in a seamless manner."
The full reportcosts $4,450 and can be ordered via the Frost & Sullivan Web site.
