RE: QOS or more bandwidth

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...

I know of someone who is trying to do a VOIP system over a wireless
network - they are having limited success, but when they did some packet
switching magic, it seemed to help some, but last I checked they are still
having issues with it dropping calls and the phone system constantly
resetting.  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 ;-)

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.
