Yes this is an option but the original question "why no low-end Gigabit phones on the market ?". Try to find a PC motherboard with 10/100 interface. Now, it's Gigabit for all, no matter if people need its speed or not. And both, IP phones and PC motherboard are 100$ products. What strikes me is that it's still not the case in 2012, for IP phones. I can live with that but I'm still a bit surprised by this remaining year after year. or are you still living with the remnants of > an old key system or something like that? > > "The journey of a thousand miles begins with a broken fan belt and a flat > tire." > > > On 2/8/2012 10:46 AM, Vieri wrote: >> Let me answer that, Carlos.
