Dialing Peer-to-Peer SIP IP 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 usually 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 configuration.
To make a peer-to -peer call between codecs we recommend both codecs use public IP addresses:
·
Find out the IP address of the remote codec being dialed.
·
Program each codec with a compatible algorithm and sample rate etc.
· Dial using SIP within the Connect menu.
· 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 (see
Configuring TCP/UDP Protocols for
more details on port forwarding).
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.
