Asterisk 1.2.37 ChanSpy Problem

Asterisk Asterisk General
#1

Hello

I have Asterisk 1.2.37 and I got some problems with ChanSpy. Basically what happens is that I cannot hear the operator or the client for some seconds … and after that it’s coming back to normal. What I saw in logs is:

Is there a timming problem ?

I saw in channel.c a limit…

#define SPY_QUEUE_SAMPLE_LIMIT 4000                     /* half of one second */

Any suggestions? I cannot upgrade to asterisk 1.4 or later…

Hard to say, 1.2 went EOL last year:

I solved the problem. It was indeed related to timing due to the fact that my asterisk was running on a xen guest. Recompiled kernel with HZ=1000 and zaptel without RTC and now it’s fine.
