Hi,
We just bought a new OpenVox 2 channel GSM Gateway (see below for HW and SW details).
We've both channels active, configured as a group.
Both ports are group members and both ports are using the "Call Duration Limitation" feature.
What happens is that if one channel reaches the threshold limit (thus "Remaing Time" = 0 in Status Page) the system won't fallback to the second port!
This is a HUGE issue that makes this feature completely useless.
