I’m about to ask a somewhat generic question that I know will require more information to fully answer so bear with me
We have noticed at times we get spotty call quality. At times the receiving voice comes in and out, and at other times the person called has a hard time hearing us. It doesn’t happen all of the time thankfully, and most of the time call quality isn’t an issue.
I first noticed this when I was uploading a big file from our network. Our PBX is in house so I assumed I was out of bandwidth. I checked out router (Netopia 3387) and it has QOS turned on for the IP address of our PBX so I’m surprised that it was affected so severely by network traffic, but oh well.
My question is whether or not there are settings in FreePBX to optimize for call quality or if it is totally dependent on our network. The box we have the PBX running on has 512mb of ram and I noticed that memory usage ranges from 94-99%. I’ve read other posts saying that this is normal and that since the disk swap is at 0% we should be fine. The processor is a 1.7 Celeron.
The version that is installed is Trixbox CE ver 2.6.1.11. I believe the FreePBX version it’s running is 2.4.
If anyone has any general advice about things I could try I’d appreciate it.
Thanks.
