    To my much regret both settingf Ring tone and Call divert are ok and switched correctly. But incoming calls are not heared at all. I have two handsets in my household . One is working properly but the second one causing these problems. Waiting your next advise.

Do you mean the ringing tone? our the Earpiece of your RTX 3088. but since you say landline too, probably you mean ringer. so when you call out, you are able to hear them and they hear you right? I will assume that the landline is inserted in the RTX 3088 base and you are using it as a 2in1. you could have muted your set. Adjust the volume via Settings ==>Tones ==> Ring tones.

    another reason could be if you have enable Call divert, which means that all incoming Skype calls are forwarded. Disable call forwarding via Settings ==> Call divert ==> Call forward.

    then that means the the ringer (hardware) is faulty or has gone loose. it can happen and solution would be opening up handset and checking for ringer looseness or replace it. this may require some tools and slight skill..otherwise, take it to the nearest phone service point . it is something very easy to fix.

    I think I have the same problem as Bison47. (I don't have a landline phoneline connected to the RTX 3088, only the network cable for Skype). With incoming calls from both Skype and landlines to my Skype In number, the handsets ring normal and show who is ringing on the display normal. However, when you answer the call there is no sound and the person on the other end cannot hear me either. If I use my PC to answer these calls, SkypeIn works fine, but answering calls with the RTX 3088 doesnot work.
    For your info: outgoing calls to landlines work fine using the RTX 3088.
    Hope someone knows what to do.

There are a few things that cause what you describe:1. The landline is having problems and your phone is trying to alert you so that you know not to use it2. The internet connection is having problems,3. You have voice mail or other notifications that wait your attention.To avoid any issues you should update the firmware on both devices.

I can't hear the phone when I receive a call. Have

I had the same problem with the latest firmware (Version 250). It was working perfectly earlier but this problem arose suddendly. I fixed it after many days by installing an older firmware (Version 245 in my case) and then installing the latest firmware again (Version 250).

You can install the firmware by going to:

Menu > Settings > Advanced > Firmware Update > All Firmware vers. > (select firmware version) > Install

Please make sure that you don't loose power and internet to your base station during the update. Also, your handset should be fully charged.

Hope this will help everyone who has the problem.

The microphone of my dualphone 3088 is working properly with the land line but not at all with skype.

You have to change te properties of microfone and speaker in the Skype to the phone.
Go to tools->options, enter audio settings and define your phone for mic and speaker.
