Is there any chip that can directly interface microphone and speakerphone
to the ethernet network?
Where can I found info on voip?
7rots51 said:It seems that agere ICs is better.
But I do not know is it necessary to write VOIP protocol stack for these ICs(they are only a hardware platform ) or all the software/hardware protocol stacks is included in the
IC,and I just configure and use it.which is correct?

Two identical stations at different locations within a LAN or WAN.
Just connect power, a PC speaker & mic and Ethernet. TX activated by a PTT switch. I/P address and other parameters configurable by a terminal via RS-232 serial port. Doesn't have to be full duplex so no echo cancellation is required.
I'm wondering if it would be possible to do using an Atmel ATmega processor with a suitable hardware CODEC and a Realtek 8019as NIC chip ?
Would an ATmega chip have enough horsepower (MIPs) to handle reading the CODEC and dumping UDP packets and keep up ?
Anyone done anything similar to this ? Ideas, suggestions etc. appreciated.
(Looking for homebrewed project ideas, not commercial VoIP phone solutions.)
Thanks.
