Hi All,

I've been reading this thread and am just not sure if I can do this. We have a Toshiba IP phone system and we want to expose a public address for remote telephones to "call" to connect to our internal system. I created protocols on our ISA 2004 firewall, similar to those above, but the phones state that they cannot find the IPU. Is it possible, using an ISA 2004 firewall, to allow telephones outside the network to connect to the LIPU?

I'm so confused... :confused:

Thanks,

Mark
