Need help with Desired Result via VPN

[jamesc]

1. Brekeke Product Name and version:
Latest

2. Java version:
Latest

3. OS type and the version:
XP or 2k - undecided.

4. UA (phone), gateway or other hardware/software involved:
Have not purchased yet.

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
Closest to http://www.brekeke-sip.com/bbs/network/pattern10.html

6. Your problem:
Can't find how to get my desired result. I thought my scenario would be common but cannot find.


I need help finding a solution for 2 and eventually 4 VPN workers. I envisage the setup would be as follows:

Existing Anolog PABX in main office
|
|
(Analog phone cable)
|
|
<Digium TDM400P or whatever is suggested?>
Brekeke Server on Windows
<Network Card>
|
|
(VPN)
|
|
VoIP phone in remote location.


We need to have the office girls transfer calls to VPN workers.
We need to have the VPN workers calling via Public PABX (ultimiately - i.e. we will only be paying one phone bill to telco - we do not want to use a third party provider).

Questions:
1. Am I on the right track?
2. What brand name / model would be suggested for the PCI card in Brekeke server?
3. Do I need anything else other that VoIP phone in remote location?
4. Would the Brekeke be an overkill in this scenario?

voice over VPN is an infant technology. once the packets hits the internet, there are no packet delivery guarantees.

the remote locations will be an issue itself, dsl, cable, address translation. wireless users....
