| Hans-G?nter@25307 | 1 Siproxd is a proxy/masquerading daemon for the SIP protocol. |
| Hans-G?nter@25307 | 2 It handles registrations of SIP clients on a private IP |
| Hans-G?nter@25307 | 3 network and performs rewriting of the SIP message bodies to |
| Hans-G?nter@25307 | 4 make SIP connections work via a masquerading firewall (NAT). |
| Hans-G?nter@25307 | 5 It allows SIP software clients (like kphone, linphone) or |
| Hans-G?nter@25307 | 6 SIP hardware clients (Voice over IP phones which are |
| Hans-G?nter@25307 | 7 SIP-compatible, such as those from Cisco, Grandstream or |
| Hans-G?nter@25307 | 8 Snom) to work behind an IP masquerading firewall or NAT |
| Hans-G?nter@25307 | 9 router. |
| Hans-G?nter@25307 | 10 |
| Hans-G?nter@25307 | 11 SIP (Session Initiation Protocol, RFC3261) is the protocol |
| Hans-G?nter@25307 | 12 of choice for most VoIP (Voice over IP) phones to initiate |
| Hans-G?nter@25307 | 13 communication. |
| Hans-G?nter@25307 | 14 By itself, SIP does not work via masquerading firewalls as |
| Hans-G?nter@25307 | 15 the transferred data contains IP addresses and port numbers. |
| Hans-G?nter@25307 | 16 There do exist other solutions to traverse NAT existing |
| Hans-G?nter@25307 | 17 (like STUN, or SIP aware NAT routers), but such a solution |
| Hans-G?nter@25307 | 18 has its disadvantages or may not be applicable to a given |
| Hans-G?nter@25307 | 19 situation. |
| Hans-G?nter@25307 | 20 Siproxd does not aim to be a replacement for these solutions, |
| Hans-G?nter@25307 | 21 however in some situations siproxd may bring advantages. |
