Why every call dropped after 5 mins?


I have been working around with a problem on the call that dropped after 5 minutes of conversation. Perhap, I have overlooked something
in the Asterisk configuration. Can anyone please advise me asap?

Many thanks in advances


Usually this is a problem with your SIP setup for your VoIP provider. I suggest you try calling phone to phone with your asterisk internally and see if the problem is still there. If not, then it is not your system.
