<DIV><FONT face=Arial size=2>I have asterisk working great on my LAN but cannot
open the necessary RTP ports on my ISA firewall server to get to the outside
world. (I must open each port manually<SPAN class=512564022-08052005> due
to an ISA limitation, and opening 10000 ports will takes weeks</SPAN>).
Ideally, I would like to reduce the number of RTP ports in use.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I noticed in rtp.conf that I can limit the range of
RTP ports. So:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. How many ports will I need for a home with
3 phones (and two external phone "lines").<BR>2. If I restrict the RTP
port range to 10000-10005, does this mean that my asterisk server will only use
these RTP ports for outgoing, but an external host may still try to contact my
server on any port between 10000-20000 if the call is initiated
externally?</FONT></DIV>
