Query: Cannot find base station.

I bought this handset as an extension to VOIP8411B/37. Unfortunately, I was not able to register the additional handset. I followed attached installation instructions and a slightly different procedure on Philips web site that involved pressing the "Page" button on the base station. The original handset started to beep like a burglar alarm while the new handset was unable to find the base station. I had to give up after several attempts.When I received VOIP8411B/37 I could not believe that Philips could produce a product that just works. Well, I was right - a single handset configuration is fine but two handset system is clearly a too big challenge for Philips. Very disappointed but not surprised.
