[Asterisk-Users] False Hangups on Asterisk

[Ruben Fagundo]

I have an asterisk server running on Redhat 8.0 with a Digium TDM400P 
w/4 FXO modules (TDM04P)

There are 2 lines going into the Digium card. One line is a Vonage 
digital line, and the other line is a Comcast voice line. I have a SIP 
Grandstream 100 phone connected to the Asterisk server.  I also have IAX 
configured with FWD.

The problem is that on occasionally, after talking for about 20 minutes 
or so, the call gets hung up and I get a fast paced busy signal. The 
caller gets dead air.  So far this has happened on incoming calls to 
either the Comcast Line, the Vonage Line and it just happened while 
makine and 800 call on Freeworlddialup.
The problem occurs on both lines for incoming calls and it just happened 
again today on an outgoing call after 15 minutes of talk.

I have tried busydetect=no and yes and neither one make a difference. 
suggestions?

/etc/asterisk/zapata.conf
 busydetect=yes
 busycount=10
