In this section:
Use the GW Sig Port window to configure a signaling port for gateway-to-gateway (GW to GW) call signaling. The gateway-to-gateway signaling is a protocol that transports call signaling messages between SBC (and GSX) instances over a TCP connection and requires that an external PSX is part of the network. The SBC supports gateway-to-gateway signaling on all platforms, including virtualized SBC SWe deployments.
The parameters to define the GW signaling port differ based on your type of the SBC platform. For cloud-based deployments of SBC SWe (I-SBC or D-SBC), the parameters include IP Var so that the IP address for the port can be specified using a metavariable rather than a static IP address. For other SBC platforms, the IP Address V4 or V6 parameter appears for you to enter a specific IP address.
Each signaling port within an Address Context must use a unique IP address and port number combination.
The SBC 52x0 and SBC 7000 systems support creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.
(This ability does not apply to the SBC 51x0 and SBC 5400 systems which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restriction.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
On the SBC main screen, go to Configuration > System Provisioning > Category: Base Provisioning > Signaling Ports > GW Sig Port.
The GW Sig Port window is displayed. The following example shows I-SBC/D-SBC output.
To create a new GW Sig Port,
Select "default" from the Address Context drop-down and "defaultSigZone" from the Zone drop-down.
Click New GW Sig Port button on the GW Sig Port List panel.
The Create New GW Sig Port window is displayed. The following example shows the parameters for an I-SBC or D-SBC deployment.
The following fields are displayed:
To edit any of the GW Sig Ports in the list, click the radio button next to the specific GW Sig Port name.
The Edit Selected GW Sig Port window showing the parameters for an I-SBC or D-SBC is displayed below.
Make the required changes and click Save at the right hand bottom of the panel to save the changes made.
To delete any of the created GW Sig Port, click the radio button next to the specific GW Sig Port which you want to delete.
Click Delete at the end of the highlighted row. A delete confirmation message appears seeking your decision.
Click Yes to remove the specific GW Sig Port from the list.
