Weird - Cannot Make More Than 2 Concurrent Calls

[inspire888]

Hi All,

We've been running vicidial for years and everything has (for most of the time) been smooth sailing.

We've recently moved from a provider who was giving us 2 trunks per line to a new provider with essentially unlimited trunks.

However.......we've noticed that beyond 2 concurrent calls, calls start failing.....as in NO ANSWER.

We're running ASTPP between ourselvers and the softswitch and even ASTPP isn't showing the NO ANSWER calls.

Logs below.

Any ideas????

Ignore that.

Found out it WAS our switch which had the restriction of 2 concurrent calls.

Increase the number and all is good!
