We have done some testing of VoIP across a 802.11b wireless connection, and it appears to be pretty decent, but it really depends on the quantity of the wireless connection. The biggest problem we have run across is jitter... Spencer **************************************************** Spencer Wood, Network Administrator Ohio Department Of Transportation 1320 Arthur E.

Is VOIP really ready for such practices as to allow business to totally rely on VOIP in this matter? ok ok a little off topic ;-) -Eric On Tue, 29 May 2001, Bill Woodcock wrote:

We did one VoIP network deployment, and I tried each of the different QoS services in IOS at that time (about 18 months ago) both in the lab and in the field, and more bandwidth was the answer then.
