[Asterisk-bsd] zaptel-bsd fxs receive audio glitches since version 26

[Kim Culhan]

Greetings-

As of the changes made between version 25 and 26 there has been
a problem with the fxs driver.

The problem is a tick at 1 second intervals in the receive audio.

The exact version where this happened was determined by using
subversion with the -r command to obtain each version from 29 back
until the problem stopped.

FWIW the ticks sound close to the same as ~1 year ago, posting
to the list there was this reply:

There is no diff between wcfxs.c version 25 to 29, is there a place
to 'browse' the subversion source ?

The system is running asterisk from HEAD updated from ~1 hour ago.

This is on FreeBSD 6.0-STABLE from 12-16-05, updating this now
to 6.1-PRERELEASE.

Any thoughts are greatly appreciated
