Hi Siddhardha,

as you already mentioned has the contact header a different format that can't 
be parsed by the parse_uri function. You can try to fix this with some 
transformation in the script, to remove the brackets before its parsed. But 
the contact could contain also some parameters, this will again break this. 
The trunk version also contains a new transformation "tobody" that probably 
could also used to extract the uri. Probably the easiest solution is to not 
use the $ct with this function. ;-)

Cheers,

Henning
