The spikes go away after unloading wanrouter modules but *before*
removing the zaptel module. Seems I have to contact Sangoma.

Another "nice" issue: after removing the af_wanpipe and the wanpipe
module the machine crashed :-(

Well, drivers evolve over the years and things can get better ;-) And
I wanted to know if there is a solution for this special machine.

I am also pretty sure that it is not the distro. I have Debian with
non-debian kernel.

Dont't know anything about TDM400 but we had some issues with Modems
which were using the Asterisk-path.

I got a mail from David Elbel. He suggested to recompile zaptel
drivers *after* installing the Sangome drivers. But that did not help.
