A few more notes: It appears that Skype and Google voice work well enough over wifi - but not SIP. So I'm starting to think that the SIP protocol stack is the problem? There are other standards - Most are proprietary, but it looks like jingle is on a BSD licenses. I can't seem to find anything that mentions the license of IAX2 ?? There are some softphones that support IAX2. Mod Opal lets freeswitch talk via IAX2 - I don't know if it is working? If anyone has tested a IAX2/freeswitch/wifi combination - I would be quite interested in the results. Squinting into the future - the question is if the new wifi standard 802.11ac or a move beyond SIP will be the solution to VoIP/wifi It does look like 802.11ac has addressed some latency issues with MU-MIMO, but I've been unable to find any real-world numbers. This is a complex new standard that will take a while to get debugged and bench marked. Could be that any wifi that has more than one connection will glitch audio - and MU-MIMO could fix that. Right now it still looks like a SIP world that we live in.. -------------------------------------------------------------------------------- Karl Schmidt EMail Karl@xtronics.com Transtronics, Inc.
