Please keep in mind that for a call recording to be possible, all the RTP media (voice packets) have to pass through the server before they reach the endpoints of a call, so the "audio bypass" has to be set to No, both on the extensions and the trunks involved in a call.

In essence, the media of every recorded call has to be subjected to the jitter and packet loss following a path, which in most cases is not optimal between the caller and person called through the PBXes server.

Can the choppy audio be heard from the people involved in the actual call, or can it only be heard on the recording of the call?

In order to be able to judge where the actual issue lies on a bad inter-networking day, we should have data from the good days. That means pings and traceroutes from the IPs of the extensions towards the PBXes server and towards the ITSP. Even when we do have the data in question, and we can pinpoint the issue on a particular network link, there is not much we can do to resolve the issue. In most cases, an upstream network provider is having an issue on one or more of their network links and is in the process of re-routing traffic, replacing equipment or repairing the physical layer.

Not much we can do, unless our ISP is having the issue, and we can complain directly to them. But even then, chances are they know about it, and trying to fix it. Unless all their network links are congested and have to increase their capacity, but are delaying it. In this case though, lots of other users of the same ISP will be complaining, so it's worth keeping in touch with other users of the same ISP.

Hi Diafora,
No problems here, recording quality is consistently good with G726 on www5.
Only comment I would make is that the recording volume can vary a lot between calls (even for same user, same ATA).

Well, if you share a couple of IPs where you have SIP UAs, I will indicate on which data-center of the two, your account should be hosted.

Karachi is currently on the www1 server.
