[asterisk-users] dropping calls in the middle of conversation
Hi all, I'm having major trouble with a simple asterisk installation dropping calls in the middle of the conversation. I recently upgraded from asterisk-1.2.3 and zaptel-1.2.2 to asterisk 1.2.10 and zaptel-1.2.7, but to no avail. The machine is equiped with a TDM40B and a TDM22B and has an MSI motherboard with an intel 915G chipset and a SATA hard disk 80 GB. It's running Fedora core 3 Linux. The situation appears with no obvious reason, the CLI shows nothing more than the zaptel channel hanging up. How should i go debugging this mess?

well, first thing, turn on debug logging in logger.conf (edit the messages line so that it includes the word debug, the file has examples to help you). then, after doing a logger reload, you will be getting quite a bit of logging...the next time a call drops, note as much about it as you can (the destination number works great for me) then search /var/log/asterisk/messages for that number. look at the information and see if any of it makes sense. we are having dropped calls with our telco (SBC) and 99% of them are on the telco's side, beyond the CO. all i do now is look for a "didn't receive frame from Zap/XX" - that tells me that the telco stopped transmitting, so asterisk hangs up the call. every one of the calls that i've had SBC trace has been terminated by the far side... check out your debug log and post back if you still need assistance. wes On 7/27/06, Giannis Margaritis <giannis.margaritis@cyberstream.gr> wrote:> > > > > Hi all, > > > > I'm having major trouble with a simple asterisk installation dropping calls > in the middle of the conversation. > > > > I recently upgraded from asterisk-1.2.3 and zaptel-1.2.2 to asterisk 1.2.10 > and zaptel-1.2.7, but to no avail.

>I'm having major trouble with a simple asterisk installation dropping callsin the middle of the conversation. I was having similar issues when we installed a new non-pri T1, one of the problems had to do with the wiring job that was done, but the major problem seemed to be related to IRQ sharing, I disabled EVERYTHING I could on the motherboard, including USB interfaces (which seemed to always be sharing IRQs with one of the Digium cards). After turning all motherboard peripherals off, the number of dropped calls fell to about 2/week, before doing this we were dropping lots and lots of calls every day.

Have you tried setting: -------------------------- Faxdetect=no Busydetect=no Callprogress=no Busycount=8 -------------------------- In zapata.conf?
