Larry, Thanks for the feedback. I have a mix of ATAs deployed, but I am going to make sure they all have the right DSCP flags set for Airmax to prioritize. I will also take your advice on sniffing and include in my testing. That way I can make sure the flag isn't getting stripped off somewhere on my network.
Anybody else with suggestions/info? I welcome all input no matter how minor or critical it may seem. -Matt -----Original Message----- From: l...@mwtcorp.net [mailto:l...@mwtcorp.net] Sent: Thursday, July 31, 2014 4:59 PM To: WISPA General List; Matt Brendle Subject: Re: [WISPA] VoIP - Who is using successfully?

It's a fairly simple engineering task that is very detail oriented. Jitter is the killer. I have and am using Cisco, Force 10, Mikrotik, UBNT, Radwin and MRV equipment. They all work but you have to look for any possible spot where there can be congestion and plan a way through. Mikrotik's are particularity difficult because they don't re-order packets. You make room by throwing something else away. Like everything Mikrotik it takes some middle to both edges thinking. Regularly sniff your voice traffic and be sure that the dscp/tos codes are there. Some switches/ providers will remove them. You can build an entire network with a pristine voice channel in it to find your voip running best effort. I have had that happen more than once. Also remember adding bandwidth on one link can create two or more new congestion points someplace else. details, details, details but once you get it right it's something to behold. > > > I know that is a rather broad question, but I want to make this work > and get our Support Calls down. > > > > Matt - NC Wireless > > > Larry Ash Network Administrator Mountain West Telephone 123 W 1st St. Casper, WY 82601 Office 307 233-8387 _______________________________________________ Wireless mailing list Wireless@wispa.org http://lists.wispa.org/mailman/listinfo/wireless
