[Serusers] loggin onto other SIP servers using username/password combo

[Iqbal Gandham]

Hi

I am using rewritehost/port to redirect SIp request to other servers, 
such as asterisk, which then can log onto remote SIP servers like FWD 
using a user/pass combo, currently I believe this is not possible in 
SER, is this by design.
