I want to estimate the amount of bandwidth required for Asterisk running

Can someone share with me any implementation experience?

What kind of T1? And what codec?

Check out http://www.asteriskguru.com/tools/bandwidth_calculator.php it
should help you figure out how much bandwidth you will need.

That sounds like an E1 to me. Is that 32 DS0 channels or 24?

That's incorrect... a T1 is 24 channels, and each channel is 64kbps.
There are also a few extra bits for framing, which adds up to 1.544
megabits per second in each direction. The audio comes across a T1 as
G.711 (not GSM as stated above), and on a T1 it's usually using ulaw
companding.
An E1 is 32 channels, and each channel is the same 64kbps. This adds up
to 2.048 megabits per second. Again, the audio is in G.711 format, but
alaw companding is typically used on an E1.

Using the online calculator mentioned in this thread will help. There
is a lot to bandwidth and even more to VoIP network traffic than can
be answered with your question. On an E1 that is dedicated to IAX
terminating to a provider that does trunking I would say that you
could get a large number of concurrent calls through.... On the other
hand if the calls where SIP u.law and going to different network
destinations you may only get a few concurrent calls to work.
Its like a good bottle of wine, the bottle is just the container....

Yes, it is actually a E1.
Your suggestion will be greatly appreciated.

Additionally Mark, a Channelized (also called Integrated) T1 offers 24
channels for voice/data, but after bit robbing (for signalling, etc) you
only get around 56kbps per channel. ISDN PRI over T1 has 23 b-channels
of voice/data and one d-channel for signalling, etc. PRI is preferred
and most common. And of course, ISDN PRI over E1 gets 30 channels of
voice/data and 2 channels for signalling.
