Two weeks ago, I woke up to the email below (I'm paraphrasing):
We're unable to search any contacts from the Trio 8800's. Can you assist?
Here's what it looks like from the phone:
This normally just works, so I was confused. The client was able to login to the phone ok and select the option to search contacts, but nothing showed up. They're using S4B Online, but I didn't see any Support Issues when checking the portal. What gives?
As it turns out, a lot of others were experiencing the same problem. This was a known issue with the 5.4 firmware. Upgrading to 5.5.2 (or above) resolves the issue. I had the client deploy the latest and greatest firmware to their lab (5.6) and confirmed the issue was fixed. They deployed to their production environent shortly thereafter.
