[Asterisk-Users] Point to Point VOIP

[Race Vanderdecken]

Greeting Jacob,
 
            Since you are new to IP I would work with an Asterisk
provider/builder if you can, you will save money and headaches.
 
            You will need an asterisk box with network cards in both
locations.
            You will need a DID provider on both ends.
 
            You do not need a channel bank, ISDN lines, ISDN cards, FXO,
FSO and all that because you are VOIP. VoIP only needs an Ethernet
connection to the internet. DID providers convert your PSTN bound
traffic for you, and you don't need to buy the equipment. DID's are
cheaper then T-1's and ISDN parts and service.
 
            Have the DID provider route your calls from his PSTN gateway
as sip to your Asterisk box. Then use the asterisk dial plans,
Extension.conf, to send calls to each extension.
 
            On the remote end use asterisk to send calls out to a DID
provider and do the reverse.
 
            Don't buy a channel bank and TDM stuff, use VOIP.
 
 
            The DID providers will collect your calls from the PSTN and
send them to your asterisk box as SIP calls. All you need to do is
register your sip phones with asterisk. Then  have  asterisk register
itself with the DID providers.
 
            Come to think of it you only need one asterisk server. Have
it register with the DID providers in the countries you want to make
calls to and receive calls from.
 
            SIP phone ------->asterisk-----> DID provider ----> PSTN 
            
            The reverse works too.
 
            To call your remote office, just dial the extension number.
 
SIP phone ------->asterisk-----> remote SIP Phone

I am looking for a setup something like the following.  I have two
offices, one located in the US and one in Australia.  I would like to
implement a solution whereby I would install a gateway in each of the
two offices.  When calls are made to a few numbers in the US, the calls
would be routed over the gateway to the one in Australia.  The gateway
in Australia would dial out to a pre-defined number/set of numbers to
complete the call.  What is the minimum hardware/software configuration
I would need to complete this sort of setup?  I am relatively new to the
concepts behind VOIP, so any help would be greatly appreciated.  Is
there anyone with a similar setup to this that has any suggestions/tips?
 
Thanks,
Jacob
