So, we have g729 set on the endpoints at that problem location. I've made a few test calls this morning. The call quality is definitely better, but you still can hear cutting out here and there.
I hear what you're saying about the VM's possibly being the cause dicko, but we have multiple sites all tied into the same server through site-to-site VPNs, and only this site has this level of quality issues.
To hone in a little deeper, out of seven sites, three of them have complained about voice quality. Two of the sites are hard to reproduce, but if you listen for a long time, you'll get some bad audio here or there. The third site, which is the one where we have g729 setup now, is the really bad one, though the new codec has made some notable improvement. The other four sound just fine. That being said, it seems like the problem might be at the provider level.
The two locations that have only had a couple complaints are both timewarner business. I've heard they limit RTP sometimes. Is there a way to work around this?
The bad location is in a fairly remote location through a provider called Ayera. They use Ubiquiti microwave antennas to get that locations a connection of 25/10Mbps. Of course I thought that the wireless nature of the circuit was the culprit originally, but after contacting their support team, they said that they had some quality score that the connection was showing, which is supposed to mean VoIP quality is great.
Thoughts?
