[Asterisk-Users] PSTN Call drops randomly - Email found in subject

[Greg Scasny]

Set busydetect=no in your zapata.conf file. That should stop the random hang-ups. If you really need busy detection, try setting busycount=8 or even 10. If you still get random hang-ups, turn off busy detection and turn on call progress. May help the situation.

Subject: [SPAM] - [Asterisk-Users] PSTN Call drops randomly - Email found in subject

Dear List members,
After succesfully installing the * on a couple of systems, and putting
them on test, I observed that there is an intermittent call drop on
PSTN line.

The systems are
- Dell Optiplex P3/500MHz/128MB
- Built-in ethernet
- 1 X100P (Motorolla chip) card on PCI
- 10G HDD etc.
- Asterisk April 17 CVS.
- 2 Mediatrix FXS ATA (4 phones)
- 2 Grandstream phones.
- sip.conf, zaptel.comnf and zapata.conf included below

Also let me know what do I need to "turn on" to get fine details about
the event when it happens.

Any help will be greatly appreciated.

Regards.
