[Asterisk-Dev] Is Asterisk the right software suite?

[Kevin K]

Hi,

I am looking to set-up a VERY simple VoIP system to enable an end-to-end 
call (TDM-IP-TDM) or possibly multiple calls.  My intention is to look into 
bandwidth-saving algorithms such as voice activity detection / silence 
suppression and RTP header compression.  I am not overly interested in other 
features such as IVR, voicemail, etc at this time.

My questions are:

1) What are the memory/processor requirements to install and run Asterisk? 
(<- this might be influenced by question 2)

2) Are the different applications and features available for Asterisk 
optional or must everything be installed to work properly?  As said, my use 
for Asterisk is very simplistic, so I'm wondering if I still need to link 
all the features that I don't need to use (e.g. those under 
usr/lib/asterisk/modules, var/spool/asterisk/vm, etc directories).

3) How long has it taken some of you to install Asterisk and get it working 
in a simple call?  (I know this is a very general question, but it may give 
me an idea for my schedule).

Thanks for the help,
Kevin
