After they start using the handset all the cut outs go away.Īfter training some of the worst complainers to pick up the handset, the number of bad call complaints vanished.

I'll tell them to pick up the phone to talk to me, I can't hear them. Half the speakerphone calls come across as cut out frequently because the user is whispering to a speakerphone and bouncing on the noise gate that shuts off the mic when the audio goes too quiet. The speakerphone has a more aggressive frequency roll off, noise gate, clip threshold, and echo cancellation (sometimes with a bit of duplex-to simplex switching) to struggle with. I have the worst phone calls with people that insist upon using the speakerphone to place all their calls. Check to make sure both ends of the phone conversation are picking up the handset and not using the speakerphone. We have this problem both on VOIP and on digital PBX systems. Solution for them (because internet is terrible in Ohio, no good fiber,FIOS, etc) was to just get a PRI dropped in and connected to the ipitomy system and lots of issues cleared right up, system is 99% solid now. What would be better is a 2 lane highway but the speed limit being 100mph, so individual cars can reach their destination faster.'Ĭheck your SLA with your provider, many will mention target latency expectations, however many are smart enough not to promise you anything with latency, because they know they can't deliver. You want to add 5 more lanes thinking it will help, but your highway is only using really one lane now. 'You have a 5 line highway where each lane is 55mph max. Also, graphing the data showed one mgrs wife called like 8 times a day, no joke, and you could tell on the calls he was annoyed.)Īnyways, the issue was latency like 80-100ms to their data center, not bandwidth, which most non-tech people don't get. (Also, props to wireshark for breaking out the calls to replay them back. Wireshark data showed that WAN was never more than like 5% utilized, and 99% of that traffic was the VOIP traffic. Anyways, same think, plenty of bandwidth and sip provider said it wasn't enough bandwidth and customer was hogging the hole WAN line for internet browsing, etc, etc. I'm not a big VOIP guy, but i have a customer with an ipitomy system that used sip trunks to i think vintalk or viniculum in texas data center? (Customer is in NEOhio).
