hi all
i wnat to implement a telephone that supports both, the basic telephony system and voip
the basic telephony system is not a hard task at all
but the main problem here is what is the hardware needed to implement voip
anybody know anything about it
anybody know any site that talk about the hardware used
thx in advance
Check Out the July, 2005 Issue of Circuit Cellar, (Issue 180). There is a design around the TI TLV320AIC22C - Dual VoIP Codec, (unless you want to build your own Codec in which you may have to get the ITU G.711 specifications).
