AW: Gatekeeper behavior question

Hans,

H.323 describes this situation in section 7.2.2. If the aliases
_and_ the transport addresses (i.e. IP address + TCP port) are
distinct, then the Gatekeeper is able to distinguish the two as
really being different.

If _either_ the aliases _or_ the transport addresses are
identical then it is up to the Gatekeeper implementation to
decide what to do.

If the alias is the same (and the transport address is not), it
is up to the Gatekeeper to decide to accept or reject the
registration. If the transport address is the same (and the alias
is not), it is advisable to replace the previous registration
with the new one.

Regards,

Frank

Hi Hans,
yes, you have to map IP address + port to an alias. The H.323 standard only
talks about "transport addresses" which have to be mapped. And a transport
address in the IP case consists of addr+port.
