After
voip.ms switched to "more secure severs" my call-waiting stutter dial tone disappeared.
I logged into my Obi202 and there's no checkmark in "MessageWaiting" under Voice Services->SP1 Service.
As usual, I unticked "Default", put a tick in MessageWaiting and rebooted, but no matter what, MessageWaiting remains unticked.
I think
voip.ms's servers now lack some crucial feature but they say no, it's a fault with the Obi.
I've tried my spare Obi200 and it's the same. I updated its firmware and it's still the same. I reset to default, set it up again and still no stutter tone.
What should I try next? Is there anything I can say to
voip.ms to point out what's lacking on their end?
ps: MWIEnable and X_VMWIEnable are enabled.
