<DIV><FONT face=Arial size=2>I am looking into supporting around 20 SIP clients
(ATAs, IP softphones, etc) distributed in around 10 different end points (in
South America). For the most part they all have narrow band connections
64kpbs, 128 at most and Iīd like to use g729 all around (donīt have too many
alternatives)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>To start with, I will have one * with no gateway to
the PSTN and eventually a few * boxes with termination at different
points.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My main concern is the bandwith I will need on the
site where * will be located. Currently I have 128kbps but what happends
if: </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1) Several users connect at the same time to check
their voicemail, or run some other app. Is there a way to limit the number
of simultaneous connections? that is can the user get a busy tone? I
think that would be better than running out of bandwith and the user
getting a bad connection.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2) Assuming all the phones are configured
for g729 (and therefore no codec translation) can I assume that the RTP
stream between any two point will no got through the * box?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>3) What kind of bandwith do
the colocation (shared) etc, ISP services in the US offer? They all
give you a monthly bandwith (ie 50GB, etc) but there is no mention of the
guarantee bandwith for hosting apps like *- Since for now i donīt need to
terminate phone calls on the PSTN, will these be a good solution (rather than
paying US150 for a 128Kpbs to host it from here)</FONT></DIV>
