Bad VoIP audio, choppy or robotic, finding the cause.
Audio issues almost always come from one of four areas: network (jitter, packet loss), codec, hardware (headset, cable) or provider. Work from close to far: phone first, then LAN, then WAN.
Try this first
- 1Test with a different phone or softphone on the same line, if the problem stays it is not the headset.
- 2Test wired instead of Wi-Fi to rule out wireless.
- 3Measure MOS score or pcap via PBX or provider portal, look at jitter and packet loss between you and the SBC.
- 4Force codec to G.711 for diagnosis so you know if transcoding plays a role.
When to bring us in
Problem only during office hours or only one direction: packet capture on both sides and pull the provider in, otherwise it stays ping-pong.
