Hi Friends,

I am implementing Asterisk PBX in our office with 180 extensions. In our office, we will make 3 calls to USA daily. We have 1 MBPS bandwidth from ISP and 100 MBPS bandwidth in our LAN. I have two doubts.

1) How much bandwidth should we allocate for making VOIP calls? What can be the projected use of bandwidth to make International VOIP calls?

2) Can I use Pentium IV system, 2.6 GHz processor speed with 512 MB RAM as dedicated Asterisk server?
3 calls a day ? How many simultaneous calls maximum to any destination ? you can probably do 40-50 simultaneous calls with the most cpu intense codecs. (g729, iLBC, speex) and 2 to 3 times more with ulaw/alaw/gsm

3) Now I am making calls to USA using Voipjet.com provider. How can I receive incoming calls through VoIP? How can I get my own incoming VoIP number?

Looking forward for your reply.

Thanks&Regards,
Chandra.
