Upgraded an IPO 500 V1 Release 4.2 to IPO 500 V2 Release 9.0400.965 using export config. Now in the IP Extension VoIP Tab the Allow Remote Extension Option is missing. Even if I create a new H323 Extension, this option is still missing in the VoIP tab. Some of the extension did have VPN Enable checked on the original system on 4.2. This is very similar to thread940-1723713 don't know if there is a resolution.
