Dialing Peer-to-Peer SIP Connections
SIP can be used to make direct peer-to-peer calls to different brands of IP codecs with public IP
addresses, or between two codecs over a LAN which do not pass through firewalls. Peer-to-peer SIP
calls are often used to connect to other brands of codecs and perform call and session management
tasks. Peer-to-peer SIP calls between two codecs are detected automatically and require no special
pre-programming.
To make a peer-to-peer SIP call between codecs we recommend both codecs use public IP
addresses. Find out the IP address of the codec being dialed and configure each codec with a
compatible algorithm and sample rate etc. If the remote codec has a private IP address then it
should be configured for port forwarding and should dial the public IP address at the studio.
