Openphone will not work, just because authentication was changed to also check for the MAC address. Reason I brought this up is I was wondering if this feature would make GnuGK more robust -----Original Message----- From: openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx [mailto:openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Zygmuntowicz Michal Sent: Wednesday, November 10, 2004 1:14 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: GK for Behind-of-Linksys Router Endpoints I think you did not undestand me. Can you use ANY H.323 endpoint, like ohphone, openphone, Cisco ATA, and it will work behind NAT? They can provide H.323-compiliant endpoints with some propriertary extensions - but the extensions are not H.323 compiliant and are not standard. How does this relate to GnuGk? ----- Original Message ----- From: "Abano, Fernando" <fabano@xxxxxxxxxxxxxx> Sent: Tuesday, November 09, 2004 6:00 PM > The endpoints are not proprietary.
