color:#1F497D'>Will you be allowing reinvites? If the server processes media,
it will obviously support less simultaneous calls. Also, you may want to
rethink the wireless portion. Odds are you will have horrible QoS problems if you
run multiple calls or mixed traffic over wireless. BTW, what do you use VPN
for? Is this for remote access or for securing VoIP calls?<o:p></o:p></span></p>

You won’t have a bandwidth problem unless you’re moving a
massive amount of traffic through your VPN or web server. You will likely have
a horrible QoS problem. <o:p></o:p></span></p>

quality audio.<o:p></o:p></span></p>
