said by PX Eliezer1:Does it relate at all to the equipment being used (PBX, ATA, IP phones, etc)?
Have you seen any pattern?
Nope, I haven't seen any pattern yet, other than a flurry of complaints over a couple of days after a couple of months of things going relatively smoothly. Indeed, that is why I posted this. I'm thinking if others are also suddenly noticing this issue perhaps we can compare notes here to try to establish a pattern.
I also don't thiink it is equipment related. Again, everything's been working for multiple customers at multiiple locations, on different ISPs, routing to different servers ... and then suddenly so many encounter the issue all at the same time.
It is perplexing, for us and also for Voip.ms support -they are trying hard to help us figure it out, and that support is appreciated.
