an E.164 number.
proxy
On executing a proxy node the Gatekeeper 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.
reject
If a reject node is executed the Gatekeeper stops any further script processing and rejects the
current call.
