14.8 SIP Proxy
SIP (Session Initiation Protocol) is a protocol for making real-time calls over IP network. Currently,
most of the SIP extensions address audio communication. AMG-2100/AMG-2101 can act like a SIP
Proxy Server, it forwards end point' requests and responses. In other words, SIP Proxy server needs to
log in the trusted registrar to verify identities of 2 clients. After enabling SIP proxy server, all SIP traffic
pass through NAT with a selective but fixed WAN interface.
In this example, client extension #301 is trying to call #303. AMG-2100/AMG-2101 asks an external
trusted SIP registrar to verify both identities. After SIP registrar responds with a YES, call is established
through AMG-2100/AMG-2101.
The system provides SIP proxy for SIP clients (devices or soft clients) pass through NAT. After enable
SIP proxy server, all SIP traffic can pass through NAT with a selective but fixed WAN interface. If the SIP
Registrar settings in SIP client is same as the system setting, when the client try to access the SIP
Registrar, system will let this client login automatically and all SIP traffic can pass through.
Configure SIP Trusted Registrar, go to: Users >> Authentication>> SIP.
