If the problem stays with the line, have you noticed any other
differences with the line? 

Just guessing here, hopefully this will give you ideas to move forward
on. There is a zapmonitor app that comes with the zapata library, it
dumps the raw audio from the line to the soundcard. Try using it to
verify if the callerid spill happens where the library is expecting it
too every time. I think on my mothers Bellsouth line her callerid
sometimes doesn't get sent till into the 3rd ring. This would possibly
cause problems as I think asterisk is set to start extension processing
after the 2nd ring. So if this is the problem, you may be able to alter
asterisk to wait for callerid spill. 

Hope this helps.
