Jitter too high for VoIP to work
I just switched from Comcast/Xfinity wired internet to T-Mobile 5G. The internet appears to work great. However, the Ooma VoIP phone does not work--incoming calls sound fine, but the person on the other end heard just a garbled mess. I ran an Ooma speed test on the T-Mobile internet and the upload and download speeds are more than fine, but the jitter is typically 50-80 ms--much higher than is acceptable for VoIP. Is there any way to reduce the jitter, or do I conclude that I can’t use VoIP with this internet?568Views0likes4Comments
