Summary: Diversion header(s) parsing
Initial Comment:
The current implementation of the parse_diversion()
header parses only the first diversion header (even if
more than one header can be present).
Also the function cannot cope with multiple URIs (comma
separated) in the body of the same header since
internally it is using the parse_to() function that
expects only one URI.

Message:
Yep it's still a problem.
I'm using kamailio v.1.4.4 and it causes some disagreement with many pstn
gateways in my architecture.
. Suffixes entered in parameters'module does not apply.
. Parsing is not working.
