Connecting over SIP

Scroll Prev Top Next More

information2

Important Notes:

1.SIP1 is enabled and configured to use LAN1 by default, which is mapped to the Primary Via interface by default.

2.SIP2 is enabled and configured to use Wi-Fi by default, which is mapped to the Secondary Via interface by default.

3.It is not possible to renegotiate the connection bit rate over a SIP connection.

4.When connecting to a Tieline G3 codec using SIP you need to manually select the G3 audio reference level. From the Home screen navigate to Audio Audio > General general > Reference Level > Tieline G3. In addition, select the following on the G3 codec prior to dialing.

•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 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 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, then tap Dialer Dialer .

Important Note: Any valid SIP server accounts registered successfully into the codec will be displayed in the Select SIP Account screen. Tap to select an account if you want to use a SIP server to establish the connection.

When you select a SIP account this will complete configuration. Simply tap Done in the top right-hand corner of the Destination Settings screen to view the Direct Dial menu screen.

10. For a peer-to-peer SIP connection select Any as the interface with which to dial if you have an Ethernet cable connected to LAN1 or LAN2, or tap Save in the top right-hand corner of the screen if it is already selected. Then tap Done in the top right-hand corner of the Destination Settings screen to view the Direct Dial menu screen.

Dialer_SIP-Select_Via_Any Dialer_SIP-Via_Any_peer-to-peer

Note: by default the codec is configured to use:

•LAN1 with the SIP1 interface if you select Primary in SIP mode, or

•LAN2 with the Wi-Fi interface if you select Secondary in SIP mode.

If you want to use a different IP interface such as Wi-Fi to dial over SIP, configure this as the Via setting in either the SIP1 or SIP2 interface. See Configuring SIP Interfaces for more information on configuring the two available SIP interfaces.

11.When configuration is complete, tap Continue in the top right-hand corner of the TOUCH SCREEN and you will be prompted to save the configuration as a program. Tap Direct Dial in the Save Program dialog to go straight to the Direct Dial Connections screen and make a connection, or tap Save & Load Program to name and save the program. The new program will be loaded automatically after it has been saved.

Important Notes:

•See Configuring SIP Accounts for instructions on entering SIP account details into the codec. If your codec is registered with same SIP registrar as the destination codec then you only need to enter the SIP user name to dial successfully.

•It is also possible to configure SIP programs using the Toolbox web-GUI. See the section titled Configure SIP Peer-to-Peer Programs for more information.
