I have a customer in Orlando and another in Venice. The Orlando customer is running PhoneManager 5.2.11 with 6.3.7.79 on the MiVO 250. The Venice customer is running PhoneManager 5.2.11 with 6.3.7.79 on the MiVO 250.
In Venice, they have analog lines. In Orlando, they have SIP trunks.
Their call flows are almost exactly the same. Both send calls to a ring group, which contains a Hunt Group Members Extension List and that ring group overflows to another ring group before overflowing to an application (CRA Auto-Attendant).
The Venice customer's ring groups work flawlessly. The Orlando customer's ring groups do not work 99% of the time.
Just before posting this, I attempted to send a call into the call flow and never saw the 3rd member of the second ring group in call activity. I am using an extension list, so all should ring at the same time.
There is 1 member in the first (as a list) and there are 3 members in the second(also as a list).
What's going on here? Has anyone seen this wtih 6900 phones on SIP trunks with MiVO 250? If so, what was the fix?
EDIT: I just tried adding members individually to ring groups and removing the extension list. That didn't help. In fact, set up this way, the call would hang on the ring group in call activity. I could hear ringback, but the call never made it to the first member...
