Re: [Asterisk-Users] Problem with call drops

I have followed the recommendations. After some further tweaking, this is the most I've been able to get: [EMAIL PROTECTED] zaptel-1.2.0]# ./zttest -v Opened pseudo zap interface, measuring accuracy... 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.000000% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8190 sample intervals 99.975586% --- Results after 41 passes --- Best: 100.000000 -- Worst: 99.975586 -- Average: 99.983029 This is on the Asterisk server which has the TE410P board (Xeon 2.4GHz, 2GB RAM, IDE HD, FC4, Asterisk 1.2.0) Now, it could just be that this machine is fine.

It's using ztdummy on a Dual Xeon 2.4GHz, 2GB RAM, SATA, FC4, Asterisk 1.2.0. Could it be that ztdummy is not good enough?

(Is it 1,000/sec on these boards too?) Moj
