I am preparing a new asterisk server to move all our phones to.
I am facing a limit of the active calls and I dont know how to determine the reason.
I have 2 trunks , one is having 3 lines and the other 2, in the Outbound routes I have place them in order and start calling, I see that I am limited to 2 active calls, the 3rd one is “All circuits are busy now” So I check on the CLI :
CLI > sip show channels
I got 4 active dialogs from one of the Trunks. then I try to dial on a 3rd phone and I see there is an invite but no call.
I limit the first trunk to 1 channel and second left to 3(what it supports) and try again, I got the same result but now the first call is from the first trunk and the second is from the second trunk, So I assume that Trunks work great, the outbound rules use both of them , but somehow something is limiting me to only 2 active calls.
How I can find out the reason ?
P.S. I have also add option “maxcalls = 255” in asterisk.conf - no difference.
