This conversation has been merged. Please reference the main conversation: Network requirements, and troubleshooting call quality (QOS) issues.

We have a recurring problem where we can't hear the person on the other end of the line for about 5 seconds. It happens on inbound and outbound calls. Sporadically , throughout the call. Any ideas?

Hey Chuck! Thanks for the reply.

We have a TP-Link TL-ER6020. with 2 AT&T DSL lines. We have 10  VX310's and 2 VX410's.

I gave the phones static IP's and put them in a QOS group w/ 90Kbps individual guaranteed bandwidth.

No special ports forwarded or anything.


Whatcha think?

Thanks!

Andrew

Is that DSL load balanced?  also what is the speed? 

Is there any cooralation of Internet usage and the call quality being bad?

Could you increase the qos to 100 or 110 on the bandwidth to see if that helps.

Also, what is your call volume like?  Has this proplem been in place from the start or is this something that just started happening?

Is there a way to verify if the QOS is working properly?.  Personally I have a physical seperation once I get close to 10 phones and also depending on the call volume.

For me it is easier to trouble shoot and with a seperate router just for voice you should not be running into these type of issues.



Thanks

The DSL like are 5 up 1.5 down each. I know I know, It's the only thing available out here. There are some fiber options but they are like $500-$700 / month and only 5X5 or 10X10.

The router is a load balancing router, but I checked the " Enable Application Optimized Routing" button which is suppose to keep the traffic on 1 WAN.

I'll try increasing the QOS to 110.

Our call volume isn't too heavy. Max 2-3 calls at a time and that's not very often. This problem has been ongoing from the start. I've done things like add the 2nd dsl line, setup the QOS, etc, to no avail.

I'm not sure how to verify the QOS. That's pushing my technological capabilities.

Unfortunately, each office only has one data port, so the cable goes from the wall to the phone to the computer...
