Use the Dsbc Sig Port - Timers window to configure keep-alive and retry timers related to recovering a D-SBC signaling link when stable calls are present.

Note:

In distributed SBC deployments, despite receiving a BYE from a participating endpoint, the S-SBC does not immediately release stable calls in the following scenarios:

  • If the connection between the S-SBC and M-SBC nodes is down, pass-through calls are not released.
  • If the connection between the S-SBC and T-SBC nodes is down, transcoded calls are not released.

In such cases, the calls are released only after the D-SBC Retry timer expires.

On the SBC main screen, go to All > System > Dsbc > Dsbc Sig Port > Timers.

Use the following table to set the parameters and then click Save.

Note

Before changing the D-SBC timer values, disable the D-SBC signaling port by setting its Mode to Out Of Service and its State to Disabled. Once you commit the timer value, revert the Mode and State back to In Service and Enabled, respectively. Refer to Dsbc - Dsbc Sig Port for more information.


ParameterLength/RangeDescription
Keepalive1-60The D-SBC signaling channel keep-alive timer in seconds (Default = 3).
