[asterisk-r2] Too many network congestions. Requested file.

Thanks,

I checked the log, and I don't think it's a problem with the tone
detection, the small delay in their response may be because they're
trying to route to number before sending us a response (like accepting
the call when the user is available, or sending network congestion
when there is no trunks available, or sending user busy etc), so I
think the dealy is pretty normal, most likely if you check successful
calls you will find the "accept call" tone is also a bit delayed if
you compare it with the other responses.

Having said that, the destiny number is exactly 1563332536 ?

Have you noticed if the network congestion happens always to the same numbers?
