OK thanks!

There _is_ and @ in the phone-context, however looking at it again it is 
strange - it looks like a.b.domain.com at domain.com this might be a config 
error would this cause the issue? Is there  a way to collect more info 
from the parser as to why its failing on a particular field?

Secondly there the fact that when this call is dropped it isnt tademmed 
onto the other leg is also a problem?
