I do not have the issues with 5897EX that Taoman had, but I do have an issue:
I have two OBis converted to 5897EX, an OBi200 and an OBi202. The 202 will not display the Call Status page. When called up, the browser waits forever for a page that never paints, regardless of whether a call is active or not. The 200 displays the data.
If someone else has a 202 loaded with 5897EX, could you check this and report? I'd like to know whether this problem is particular to my OBi or one that affects all 202s.
