Hi all,
So I'm trying to work on this complex fax server setup, and part of it involves
connecting my asterisk server to my Rolm CBX switch, via a T1 line. I plan on
using Asterisk simply as a T1-PRI Bridge to IAXmodem (which in turn, activates
HylaFax+ to handle the faxing). So far, though, I don't think I'm getting 100%
of the way there. When dialing the fax extension from my Rolm phone, I get
several seconds of silence followed by error tone. But on asterisk's CLI, I
see this:

-- Starting simple switch on 'Zap/3-1'

The Rolm gives me error tone just before the "Starting simple switch" messages
begin to appear, so it's almost like the Rolm is not waiting around long enough
for the asterisk server to answer, before it jumps to the next configured T1
channel, runs out of channels (I only configured four in the Rolm and on
asterisk).
Here's my configuration for asterisk. Is anything amiss by chance?
Standard T1
Signalling is E&M Wink, 200ms wink time (as far as I can tell)
Mode is ESF and format is B8ZS
/etc/zaptel.conf is:
span=1,1,0,esf,b8zs
e&m=1-4
loadzone = us
defaultzone=us
/etc/asterisk/zapata.conf is:
[trunkgroups]
[channels]
language=en
context=default
switchtype=national
signalling=em_w
wink=200
channel => 1-4
usecallerid=yes
callerid=asreceived
cidsignalling=bell
hidecallerid=no
callwaiting=no
usecallingpres=yes
callwaitingcallerid=no
threewaycalling=no
transfer=no
canpark=no
cancallforward=no
callreturn=no
echocancel=yes
echocancelwhenbridged=no
echotraining=800
rxgain=0.0
txgain=0.0
group=0
busydetect=yes
busycount=6
faxdetect=incoming
/etc/asterisk/extensions.conf is:
[general]
static=yes
writeprotect=no
clearglobalvars=no
[globals]
CONSOLE=Console/dsp ; Console interface for demo
TRUNK=Zap/g0 ; Trunk interface
TRUNKMSD=1 ; MSD digits to strip (usually
1 or 0)
[fax-in]
exten => s,1,Dial(IAX2/iaxmodem0/${EXTEN},10,r)
Thoughts?
Thanks!,
