[asterisk-dev] Request for testing: New wctdm24xxp and wcte12xp drivers.

Hi All,

This is a request for testing for users of Asterisk 1.4 or 1.6 with any 
of the following Digium VoiceBus based cards: TDM2400P, AEX2400, AEX800, 
TDM800P, TDM410, TE120P, TE121, and/or TE122.

 From a practical standpoint, this branch should allow these boards to 
work in more systems / configurations where IRQ misses caused problems 
in the past.

The updated wctdm24xxp and wcte12xp drivers are based on Zaptel 1.4 and 
work by dynamically increasing the latency they add to the data stream 
in 1ms increments until it does not detect any additional IRQ misses. 
For example, if your TDM800P card was sharing an interrupt with your 
disk controller and you were experiencing problems, this new driver 
could, at the cost of a few extra milliseconds of latency, allow the two 
boards to peacefully coexist on the same IRQ.

Please feel free to checkout the code on any test servers you may have 
and let me know any results. Both the good and the bad are welcome.

To get the code:
svn co http://svn.digium.com/svn/zaptel/team/sruffell/voicebus

Many thanks,
