As has already been documented on IRC, a change was committed to 
chan_zap to make these messages appear at a level lower than 'debug'. 
(bug #4107)

The purpose of this was to make people actually aware that the Zaptel 
drivers were not accepting data they should be; if this is happening on 
your system, then it seems to be reasonable that we need to find out why 
that is happening, since the drivers should always be able to accept 
data from chan_zap.
