Voices choppy in upstream direction
BobN54:
I'm using an OBi200 with the OBiWiFi adapter connected to a shared WiFi hotspot at an Assisted Living Facility; thus I have no control over the WiFi or router setup. Signal strength is good, and speed test indicates 13.5 mbps down/1.5 mbps up. Voices are choppy upstream (outbound) through either GV or voip.ms; no problem downstream. Are there any settings on the OBi I could tinker with to solve this issue? I realize my options may be limited.
drgeoff:
1.5 Mbit/s should be more than enough not to induce chopping. But how are you measuring that? What is the actual rate the Obi is getting?
cluckercreek:
Are you on Satellite? If so, then there is nothing you can do for this due to the latency.

I used a speedtest site to get the up/down speeds. How can I go about determining the actual rate the Obi is getting?
The ISP appears to be Verizon Business DSL, which is consistent with the 13 down/ 1.5 up in the speedtest.

The question here may be how many people are using the 1.5 Mbit/s upstream at any one time. At busy times the bandwidth actually available to the OBi may be very limited for a few seconds at a time, therefore voice sounds "choppy". Is it possible to compare busy times with quiet times when others are unlikely to be using their computers?
If it only happens at busy times, then it may be worth looking at forcing the OBi to use a CODEC that uses a narrower bandwidth. For example you may experiment with the voip.ms route by forcing the OBi to use the G729 CODEC. Dial *4729 (you will get dial tone after the 9), then dial whatever you normally dial for a voip.ms call. This should force the OBi to use the G729 CODEC, which will use less bandwidth.
The above will not work with GV as I don't think it offers G729 in its choice of CODECS. However, if the G729 works with voip.ms, then we can make some more permanent changes to CODECs for both GV and voip.ms.
