Signaling Point Timer Profile

Each Signaling Point Timer Profile object is a child of the Signaling Gateway object.

The Signaling Gateway has associated with it a Signaling Point Timer Profile. The Signaling Point Timer Profile defines the characteristics of the Signaling Gateway. You can delete a Signaling Point Timer Profile only when it is not associated with the Signaling Gateway.

A default Signaling Point Timer Profile named "Default" is supplied with the MetaSwitch VP3000. The default profile should be suitable for most applications.


The default profile is read-only; you cannot delete, modify, or disable it. If you want to use different values, you must create a new Signaling Point Timer Profile and change the Signaling Gateway to specify the new profile name.
