[Asterisk-Users] Booting error - Unable to specify channel 2: No such device

Hello All,
I am getting a set of errors when I boot Asterisk that I have not been able to 
solve.  What is causing these error(s)?

[Asterisk-Users] Booting error - Unable to specify channel 2: No such device

Hi ..
This may seem odd, but this problem is reminescent of the
troubel I had when first starting [*] on my test setup.  Two
suggestions.  (a) on loading the modules make sure you
explicitely load in the following order (forget modprobe)
insmod zaptel; insmod wcfxo; insmod wcfxs;  Do a ztcfg -vvv
to confirm & start [*].  (b) in my zapata.conf, I foumd it
useful to put group=1 on top for the FXO channel and group=2
for FXS, i.e. see below:
;
; Zapata telephony interface
; Configuration file

[channels]
context=inbound-calls
language=en
musiconhold=default

group=1
signalling=fxs_ks
echocancel = 64
echocancelwhenbridged = no
echotraining=yes 
rxgain => 20%
txgain => -5%
channel => 1

group=2
echocancel = no
signalling=fxo_ks
mailbox = 2100
channel => 2
------------------------------
Now it works every time.  
Hope this helps
Willy
