Dialing SIP Connections
SIP can be used to make direct peer-to-peer or SIP account calls to IP codecs configured with
public IP addresses, or between two codecs over a LAN. Peer-to-peer SIP calls are often used to
connect to other brands of codecs and perform call and session management tasks.
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.
To dial using a SIP account it is necessary to add a SIP account and register it to the codec. See

address over SIP. STUN settings are prioritized and used if both are configured.
