Title: Do not buy this
Review: I bought one unit in late 2007, the speech quality using the microphone on either VOIP or landline was dreadful but at least it was OK with a headset, until both the headset and mic stopped working. Frys replaced the unit in July last year, but now the headset is not working again. Frys will not replace it again and Philips demand you return the entire heavy package (two transformers etc) and will not refund postage. It is going straight in the bin as this is the most cost-effective solution I think.
