[asterisk-users] UK BT ISDN30e PRI Problem

So a quick update on this since I haven't had any feedback... I've
just grabbed the latest trunk from the digium subversion repo; I've
completely cleaned out the asterisk server and rebuilt from scratch
with CentOS 5, all pre-reqs have been yum installed and the whole box
has been yum update'd.

I've built the latest trunk of libpri with no errors... I grabbed a
copy of the latest zaptel redfone source and copied the ztd-ethmf.c
from there into the appropriate source dir in the zaptel code I got
from digium... I added the module to the makefile and then built and
installed it. This again went without issue...

I have just built and installed the asterisk trunk I got from the
digium svn, and I have just ftp'd all the config files I had altered
back onto the server, so sip.conf, iax.conf, extensions.conf, etc; are
all exactly the same as they were before... I am waiting until out of
hours tonight >6pm GMT to test to see if these versions on libpri,
zaptel and asterisk fix the issues; and I will update the list to
reflect either my success or failure :/

Thanks guys

Mike
