I'm trying to access the internal web server on any one of our 250 Intertel 8622 phones and can't seem to get it to resolve. It is enabled in each one of the phones via the DB Studio and I even hopped on the same subnet just in case. The page doesn't even resolve so the login prompt never pops up.

This worked when it was implemented two years ago, but I haven't been able to access it since. Telnet doesn't work either. Am I missing something? Are they using a specific port?
