Thanks again but my "scenario" is being developed for academic purposes so I afford limited resources..Furthermore the server has not a free PCI slot so I can not add any second interface..SIP packets are of higher priority comparing to the other data

I would test that under load and see what kind of QoS you get. If you have mixed traffic streaming and non-streaming coming from the server, you will need 802.1p and an 802.1p compatible router. If possible, you may want to add a second wireless interface, bind asterisk to that interface, and have each wireless interface log into its own VLAN. Then you can use 802.1q and priority queuing to give the asterisk VLAN priority over the data VLAN when the remote access and webserver will operate. Everytime someone is on your VPN or hitting your webserver, your call quality will likely be impacted without a separate voice VLAN or 802.1p. -------------------------------------------------- Salvatore Giudice [EMAIL PROTECTED] VoIP Security Training, LLC http://VoIPSecurityTraining.com 848 N.

Thank you for the reply..VPN is used for remote access and for secure data transfer..The web-server does not have a lot of traffic..I use SIP and there is a grandstream gateway with 4 FXO..I think that 25 calls is a good number.. ________________________________ Από: [EMAIL PROTECTED] εκ μέρους Salvatore Giudice Αποστολή: Τρι 01/05/2007 19:14 Προς: 'Asterisk Users Mailing List - Non-Commercial Discussion' Θέμα: RE: [asterisk-users] How many users can be supported simultaneously? 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? If you are running SIP/G.711, you will need roughly 82.4 kb/s bandwidth. 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. My best guess is that you could push approximately 25 simultaneous calls with no codec conversion, but I wouldn't expect good quality audio. -------------------------------------------------- Salvatore Giudice [EMAIL PROTECTED] VoIP Security Training, LLC http://VoIPSecurityTraining.com 848 N.

I have a pc with the following characteristics: Pentium IV 2.4Ghz HyperThreading 512 MB PC3600 Dual DDR RAM Seagate 80GB SATA HDD 4-port ethernet 10/100 PCI Card Netgear MA-311 802.11b Wireless Card On this machine runs a VPN server, an Apache server and an Asterisk Does anyone know or have experience about the number of users that could be supported for VoIP at the same time?It is a Wireless Lan over 802.11b I have checked in wikipedia but I did not find something Thanks
