I stared to have exactly the same problem - very soon after enabling the busydetect=yes in zapata.conf.
Used to work flawless with it set to 'no'. The only reason I turned it on was I was trying to busy line detection and auto redials. Ive set it back off at the mo - just to be sure that is the only problem.
TBH - Unless it drasticly alters the way * works for me (this is a very simple home set up here - nothing at all complex!!) I'll leave it set off...
That is unless someone else suggests what may be wrong...

Hi,
I have successfully configured and built Asterisk and now it is working fine from the functionality point of view as sometimes we are getting dropped calls.
The problem I am getting with POTS lines even if I receive/make a call from a sip or analog phone is that the call may be dropped randomly in the middle of the conversation, some times you can speak for 30 min, some times it drops or hang up at the start of the conversation.
I have investigated in wiki and mailing lists deeply and have played with busydetect and callprogress in zapata.conf without success.
I am currently using busydetect=yes with busycount=5 and I have tweaked the busy tone with Venezuela tone information and it works great. I have deactivated callprogress according to wiki and comments on problem on non US lines.
I have also found that modifying the rxgain and txgain seems to lower the number of false hangups but does not eliminate them.
I read on the mailing list that there are some buggy TDM400P cards out there that cause random hangups. How can I determine if this cards are the buggy ones or the problem is other ?
Zttool reports Wildcard TDM400P REV E/F.
Asterisk is running on Red Hat 9 dual Pentium III 400 Mhz with 128 Mbytes of RAM and 2 TDM400P cards with the following configuration:
