Hi,

My friend is constructing an ISP that provide data, video
and voice services. He wanted to know a little bit
information on how do the big ones such as ATT, Verizon,
Sprint, Comcast design their infrastructures to support
Voice and Video.

Any pointer will be very appreciated.

Thanks,
Jingshao

Right now we're using Asterisk, Bluetop/Blonder Tongue, and cable modems
with a sip interface to provide
triple play in large apartment complexes 300+ units). not really core
infrastructure but the phones have to ring.
