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.
1. To dial peer-to-peer press the HOME button to return to the Home screen, select
Connect > IP > SIP .
2. Use the numeric KEYPAD to enter the IP address of the codec you want to dial, using the
or buttons to enter the periods in the IP address and use the RETURN button
to delete numbers already entered.
3. Then press the down navigation button to select Setup and press to adjust the
algorithm, jitter buffer and encode/decode direction if required.
4. Press the RETURN button to navigate backwards to the Connect SIP screen.
5. Press the CONNECT button to make a connection.
Dialing SIP Addresses

address of the codec you want to dial. Use the or buttons to enter the periods in the SIP
address and use the RETURN button to delete any numbers already entered. Alternatively, if
you have dialed the SIP address previously, press the RETURN button to view the Recent
Call screen and select the SIP address you want.
