1 Siproxd is a proxy/masquerading daemon for the SIP protocol.
2 It handles registrations of SIP clients on a private IP
3 network and performs rewriting of the SIP message bodies to
4 make SIP connections work via a masquerading firewall (NAT).
5 It allows SIP software clients (like kphone, linphone) or
6 SIP hardware clients (Voice over IP phones which are
7 SIP-compatible, such as those from Cisco, Grandstream or
8 Snom) to work behind an IP masquerading firewall or NAT
9 router.
11 SIP (Session Initiation Protocol, RFC3261) is the protocol
12 of choice for most VoIP (Voice over IP) phones to initiate
13 communication.
14 By itself, SIP does not work via masquerading firewalls as
15 the transferred data contains IP addresses and port numbers.
16 There do exist other solutions to traverse NAT existing
17 (like STUN, or SIP aware NAT routers), but such a solution
18 has its disadvantages or may not be applicable to a given
19 situation.
20 Siproxd does not aim to be a replacement for these solutions,
21 however in some situations siproxd may bring advantages.
