So I use the DUALPhone 3088 as my regular home phone, and I picked up the handset today and there was a screen telling me new software was available. We've already had a couple of updates from RTX, the Danish makers of the DUALPhone 3088, so I was happy to see that they keep on working to improve their product.

According to this release note, the main improvements in v115 are:

• Some fixes to the phone's ability to reconnect when the signal from the router or basestation is lost
• Improved caller ID performance and phonebook lookup
• Improved audio performance

I installed the update with absolutely no problems, and it took about 20 minutes in total. So far it's difficult to notice any improvement, but I have noticed a couple of occasions when the 3088 has made a bit of a meal of reconnecting after my slightly dodgy cable internet connection has dropped.

The important thing to remember, as with any firmware upgrade, is DON'T SWITCH THE PHONE OFF while the firmware is updating unless you absolutely have to! This can be really bad news for a phone (I should know - I did it with my last Windows Smartphone!). As RTX say:

If your phone displays “Downloading” for more than 20 minutes, re-power base and handset, sign out from Skype and try updating again. DO NOT remove power from base if display shows “Updating handset” or “Updating base”.
