Thanks for that info.

As far as I know there are about 20 touch panels and a Barix or two at the gate(s).? I am under the impression that at this count, the RAVA SIP functionality will work without any additional hardware such as a SIP server.? If that is incorrect it would be good to know.

I'd recommend Avlinkpro.? They can build custom SIP servers for any situation.
