==========================================================================

and then after so many "reason (8) Congestion (circuits busy)"
This issue reproduce regular interval...

Due to this I have so many call loss since last two week..

I earlier post this error( ID 13391) but at that time i closed issue
because i found server have limited capacity...but this time server is
fully capable...

I dont know why this happen ... I have many log ...if you require i upload
here.

Waiting for best reply.
