[Asterisk-Users] Error with WCFXO and WCFXS

[tmassey at obscorp.com]

Hello!

I have had a problem getting the TDM400P and X101P working together.  I 
followed Wipeout's handbook (I'm running RH9) and the Asterisk FAQ and I 
got the X101P working.  However, adding the TDM400P just would not work.

When I added the board and adjusted the zaptel.conf to match the 
X101P/S100U configuration FAQ, I got the following error:

ZT_CHANCONFIG failed on channel 1: Invalid argument (22)

The problem was that wcfxs was getting loaded before wcfxo, so I had to 
reverse the channel numbers in zaptel.conf.  That got the first channel 
configured, but not the second:  I got a very similar error:

ZT_CHANCONFIG failed on channel 2: Invalid argument (22)

I tried everything I could think of to no avail.  At that point, I called 
Digium and spoke to Martin.  His suggestion was to reverse the loading of 
the modules in /etc/init.d/zaptel .  I did this, restored the zaptel.conf 
channel numbering to match the FAQ and rebooted.  Interestingly enough, no 
problems.

He said he's going to change the default in the zaptel script to load 
wcfxo, then wcfxs.  This seems to work:  at least Asterisk is now loading 
with both boards showing up as configured in ztcfg/zttool.  However, it 
certainly seems to me that it's treating the symptom, not the problem.

Either way, it works here.  I just wanted this to be in the archives for 
the next poor soul who has a similar problem.
