We have a SOHO account with an allowance of 2000 minutes per month, of which we typically use less than 400. I noticed some time ago that two of our three extensions were unable to call each other, though they could make and receive all other calls. Rebooting the phones (Grandstream GXP2000) made no difference, and the problem remained unresolved.
Some time later I was looking at the status panel and could see an ongoing call between the two problem extensions. Finally figured out how to kill that call using the Status panel. We have now received a demand to pay up the equivalent of 10 months SOHO subscription for this one FAKE call or be cut off!
The demand comes from a no-reply address and suggests contacting PBXES through the support link - i.e. buy support time in order to respond.
Please don't cut us off! The 194 hour call seems to be a bug on the PBXES side!
