[Serusers] rewriteuser with something appended

[Ricardo Carvalho]

Hi,

How may I append some digits (like "_digits") to the Request-URI of 
INVITE messages?
With rewriteuser("_digits") an INVITE line like:

INVITE sip:user at domain:5060;transport=udp SIP/2.0

results in:

INVITE sip:_digits at domain:5060;transport=udp SIP/2.0

and I what to result this:

INVITE sip:user_digits at domain:5060;transport=udp SIP/2.0


Any suggestion?

Thanks,
Ricardo.
