Important Note: 1.SIP interfaces are disabled by default. 2.SIP1 is configured to use LAN1 by default. 3.SIP2 is configured to use VLAN1 by default. 4.It is not possible to renegotiate the connection bit rate over a SIP connection. 5.When connecting to a Tieline G3 codec using SIP you need to manually select the G3 audio reference level. To do this select SETTINGS •Select either a mono or stereo profile •Select [Menu] > [Configuration] > [IP1 Setup] > [Session Type] > [SIP] •Select [Menu] > [Configuration] > [IP1 Setup] > [Algorithm] > [G711/G722 or MP2] |
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
Use the KEYPAD to enter any combination of alphabetic and numeric characters in the SIP 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.
Dialing Using a SIP Account
To dial using a SIP account you first need to add a SIP account and register it to the codec. See Configuring SIP Accounts for more info.
1.Press the HOME button to return to the Home screen, select Connect > IP > SIP.
2.Then press the down navigation button to select Setup and press .
3.Navigate down to Account and and press .
4.Navigate to a registered SIP account and press .
5.The SIP Account is now selected and the codec will attempt to establish the connection via a SIP server.

Important Notes: •See Configuring SIP Accounts for instructions on entering SIP account details into the codec. •If you don't save the program during configuration, a temporary program is created after you dial the SIP connection for the first time using the codec KEYPAD. The temporary program will appear in the recent calls list if you want to redial the program.
It is also possible to configure SIP programs using the Toolbox web-GUI. |
