Siproxd is a proxy/masquerading daemon for the SIP protocol. It handles registrations of SIP clients on a private IP network and performs rewriting of the SIP message bodies to make SIP connections possible via a masquerading firewall. It allows SIP phones and soft phones (like kphone, linphone) to work behind an IP masquerading firewall or router.
How to install and configure siproxd (SIP proxy daemon)
Under 'System' -> 'Packages'
