We have a little issue at one of our sites... when i ring I get the ring alert back to me and wait for some one to answer, the other side the user picks up the phone and hears nothing. after a period of time i then get a message from our provider telling me that the call has hung up... pretty strange. I have the debugs and will paste them, if anyone could help it would be much appreciated.
I have only been testing it on one number so far, but apparently its more. the attachment before is all the info for that specific number. hope this helps.
