Wireless internet drops when receiving or making phonecall

I have an Orange Livebox connected wirelessly to my laptop. Everything's been working fine until the last few weeks. Whenever I receive or make a call using my iDECT s2i cordless telephone the internet drops and it takes ages to reconnect. I've checked all the connections and every phone socket has an ADSL filter. I understand that some wireless devices can affect a router and that these are usually 2.4ghz devices but I have no idea if my cordless telephones are 2.4ghz or 5.8ghz or indeed if this is the source of the problem at all.

Try other cordless phones. If any of the other cordless sets work, you've found the problem.

The interesting part is how makers will respond to you about this.

Does your wireless phone use the VoIP connection of the orange box or does it plug directly into a normal wall phone jack. It is unlikely it is wireless interference you phone runs at 1.9g.

If you are using the VoIP port I would be looking at the router as the cause.
