Hi Guys. Using managed networks usually provide pretty good quality and a decent MOS( mean opinion score) However, depending on the routing and if the network has provided priority to VoIP calls (managed network) the “toll quality” sound may not get there. Chopping is usually due to latency and that can be enhanced with silence suppresion ON. But silence suppresion saves bandwidth. Remember depending on routing, the latency can build when more devices (routers) are in the media stream. Also I don’t know if you can ( especially with a dialup), but you may want to see if you can adjust the multiframe count to around 3. This is usually a good spot. (3 frame of voice data with 1 header)
