If you watch de output of dmesg or /var/log/messages, you will find that a module of the
digium card failed to inicialize. Fix that, maybe you are trying to use a TDM400 with de
wcfxo module or the other way arround. 
For de TDM400 use allways (and only) the wcfxs and for the TDM100 the wcfxo; if you don't
have the other card don't load the module because you may end with an errors one of them
like this one:
unable to use trunking on channel IAX2 because there is no timing information from HW
(the error is not a transcription only a hint), also the error could be in the voicemail
or the music-on-hold.
