Creating a New Peering Trunk
Click the Create connection button
Label: Enter a name for the connection/trunk in the Label field (mandatory).
The label field is an alphanumeric field, underscore, dash and full stop are also supported.
Connection Type: Select the SIP Peer Connection Type from the drop down menu and complete the settings form as appropriate.
Enabled: Turns the SIP peering connection on or off.
IP Address 1 (Port 1): First IP/Port. This is tried first when the load‑balancing method is set to Sequential .
IP Address 2 (Port 2): Second IP/Port. This is tried second when using the Sequential method.
IP Address 3 (Port 3): Third IP/Port. This is tried third when using the Sequential method.
Load Balancing Algorithm: Sets load balancing logic for connection.
- Sequential: Attempts each reachable IP/Port in order, starting from the first.
- Round Robin: Distributes calls evenly across all configured reachable IP/Ports, cycling through them one by one.
Enable Failover Polling: Sends SIP OPTIONS messages to each IP/port to detect when a configured UA becomes unreachable. Recommended for fast failover instead of relying solely on INVITE timeouts. The UA must support SIP OPTIONS to use this feature.
Default CLI Number: Used when the presented CLI does not match any valid CLI on the account.
Transport: Specifies the transport protocol for SIP signalling. TLS provides encrypted signalling.
Encrypt Media: Forces the use of SRTP (Secure Real-time Transport Protocol) for encrypted media. This should be paired with TLS for fully encrypted signalling and media.
SIP Message Number Format: Sets the number format used in SIP messages to your user agent - options are National, E.164 & +E.164.
-
National: Regional Formal
-
E.164: Country code format
-
+E.164: Country code format with prepended +
DTMF Mode: Forces the DTMF method the proxy will use for this connection.
Codecs: Enables selections of codes to support on the connection.
Editing a SIP Peer Trunk
Once your connection is created it will appear in the Voice Connections list for your account and you will have the option to edit the connection or to assign numbers to the connection.
ID: 2talk will assign a unique ID to the trunk for identification purposes.
Label: Connection Name, this field can be edited
Type: Indicates connection type. This cannot be changed once the trunk is created
Enabled: Indicates if connection is enabled or not
Trunk State: Trunk State Deploying means your connection is still in the process of being on the voice platform. The state will show as deployed once it is ready to route calls.
Actions: Edit connection settings or Assign numbers to the connection
Notes
For new Lyra Voice Connections 2talk will assign a pilot number to your trunk as part of creation, there is no charge for this number. If your trunk is migrated this behaviour may differ.
Once a trunk is created you cannot edit:
Create Date
Trunk Type
Pilot Number
Assigning Numbers to your Trunk
You can assign numbers at Account, Group or Individual number level
Account Level: If you select this option all numbers provisioned on the account will automatically attach to the trunk.
Group Level: If you select this option all numbers assigned to the selected group will automatically attach to the trunk
Number Level: If you select this option you can assign individual numbers on the account to the particular trunk.
Remove existing Child Assignments: Checking this box will set the trunk back to an account level assignment and any Group or Number level sub settings will be removed
