I've got some accounts experiencing the same issue, only on voipo to voipo calls.

I've got a ticket open on it, and it's been open for about 5 days now.

I suspect there's a bug that is affecting multiple users.

I've provided specific call examples, so hopefully voipo's development team can resolve it.

Be patient, provide examples, and they will most likely get it sorted out.

Closing the ticket doesn't help anyone.
