Re: [Asterisk-Dev] Bug 4301 - ztdummy accuracy problem

Tue, 18 Oct 2005 03:10:34 -0700

Hi,
  I am also getting same problem with zaptel 1.20-beta1 version tar.gz file.
  It's running on linux 2.4. For this, kernel timer is changed to 1ms and ztdummy is modified accordingly.
  Is there 4301 bug with tar.gz file from asterisk.org?  Is it needed to check out 1.2.0-beta1.

Thanks,
Surendra.

 Chih,

The bug was closed because the ztdummy behavior is not the specific cause
for the delay problem. That patch with USE_RTC was intended to make use of
the real time resource available within the kernel >= 2.6.13 instead of
relying on a OHCI USB resource which was the case previously.
    

ztdummy uses the kernel's internal clock for kernel 2.6 even without
USE_RTC . with USE_RTC you should expect to get better accuracy, though.
