TANDBERG Border Controller User Manual

The not-present node is executed when the address speciﬁed in the address-switch was not present in the call setup message. This form is most useful when authentication is being used. With authentication enabled the Border Controller will only use authenticated aliases when running policy so the not-present action can be used to take appropriate action when a call is received from an unauthenticated user (see example in section 8.4).

8.2CPL Script Actions

8.2.1 location

As the CPL script runs it maintains a list of addresses (H.323 IDs, URLs and E.164 numbers) which will be used as the destination of the call if a proxy node is executed. The location node allows the location set to be modiﬁed so that calls can be redirected to different destinations.

At the start of script execution the location set is initialized to empty for incoming calls and to the original destination for outgoing calls.

The following attributes are supported on location nodes

Clear = "yes" "no"

Speciﬁes whether to clear the current location set before adding the new location. The default is to append this location to the end of the set.

url=string

The new location to be added to the location set. The given string can specify a URL (user@domain.com), H.323 ID or an E.164 number.

8.2.2 proxy

On executing a proxy node the Border Controller will attempt to forward the call to the locations speciﬁed in the current location set. If multiple entries are in the location set then they are treated as different aliases for the same destination and are all placed in the destination alias ﬁeld. If the current location set is empty the call will be forwarded to its original destination.

It is important to note that when a proxy node is executed script execution stops immediately i.e. there is currently no support for the proxy outputs busy, noanswer etc.

8.2.3 reject

If a reject node is executed the Border Controller stops any further script processing and rejects the current call.
