For a year I had been successfully using VOIP on TMHI with an OBI200 and VOIP.MS. My VOIP stopped a couple of weeks ago.
After spending hours with VOIP.MS support (very helpful support, stuck with me!) and replacing the OBI device with a Grandstream HT801, I’ve still not been able to get VOIP to work.
The support team and internet searches point to TMHI as the problem., They changed something recently. TM support is no help, and denies any problems with VOIP services. Their solution is to reboot!
I’ve tried forum suggestions about using encrypted connections, with no luck.
Before I cancel TMHI, any help?
