Unless my brain did melt down under the
high heat here, there are a few things I would share : -
1 channel u-law uses at least 80k because of encapsulation So,
think about compression -
You can never use 100% of a bandwidth. (80% is a good max) -
The values given are maximum values, far from the guaranteed values -
Instead of adsl, I would go for sdsl (symmetrical) Where adsl is possible, sdsl is normally
also possible Sdsl is more expensive but you can demand
sla, higher guaranteed bandwidth (up to 50 or 100%) Never forget that the guaranteed bandwidth
is between your router and the first equipment of your provider. You get NO warranty you have that
bandwidth further away even on your isp backbone. Isp sales men always forget to talk about
that If they say you get 100% to use all the
time, sign immediately IF they put that WRITTEN alongside financial
compensation if they fail. Dear mister sales man, you do not have to
worry about compensation since you guaranteed it would not happen ;-) Other problems you will face with several IP’s
: Even if you can manage several IP’s
for the outgoing traffic, you cannot for incoming traffic as those are unaware
of your situation Or they need to put multiple entries for
you asterisk and try those sequentially Or you could go up for incoming calls and
down for outgoing calls That is a simple solution, that will
statistically work but NO warranty NOT really a telco way Routing problems might occur … Regards, T. Jacobson --
