What are the specs on your server(CPU/RAM/drives)?

What kind of T1/E1 card are you using?

What version of Asterisk and zaptel?

I think we might be having a similar issue here at our office.

Are you recording all calls?

Does this happen with only one agent on the server dialing?

What is the loadavg when this happens?

Posted: **Wed Mar 04, 2009 5:59 am**

Hi matt,

Are you recording all calls?

Ya, Recording of all calls happening.

What is the loadavg when this happens?

load avg:- 2.3%

Thanks
Arvind

Posted: **Wed Mar 04, 2009 6:05 am**

is that a 2.30 loadavg or 0.23?

Posted: **Wed Mar 04, 2009 7:08 am**

Hi Matt,

Sorry,

load avg:- 0.23%
but it always change sometimes 0.23 or sometimes 1.6 .

Thanks & regards

What is the CPU on your server?

Posted: **Thu Mar 05, 2009 12:02 am**

Hi,

Processor is xeon -2.0 GHZ

Thanks & regards
Arvind

if that is a single core CPU then your problem may be happening when you get up to 1.6 (160% of CPU use) which can cause all sorts of problems.

Posted: **Fri Mar 06, 2009 12:11 am**

Hi Matt,

It is quad core processor.

Thanks & regards

OK, well load isn't your problem, it could be because you are recording all calls, or it could be an issue with your GSM channelbank. I don't have any firsthand experience with those.
