On a new set up Centos 4.4, kernel 2.6.9-42.0.2.EL, yum updated, 2
BRI-HFC cards, no digium hardware.

modprobe zaptel and modprobe ztdummy are both in rc.local, and lsmod gives:
[root at asterisk ~]# lsmod
Module                  Size  Used by
ztdummy                 3924  0
zaptel                206852  5 ztdummy

When asterisk starts it logs warnings:

Sep  9 20:28:00 WARNING[2645] res_musiconhold.c: Unable to open pseudo
channel for timing...  Sound may be choppy.
Sep  9 20:28:02 WARNING[2645] chan_iax2.c: Unable to open IAX timing
interface: No such file or directory

I've Googled the error message, but to no avail. Any thoughts, please?
