We have the need for customers to connect anywhere in the world to our network, directly to our network. We currently have two seperate systems working two very different missions, but a similar operation. They both have to provide secure dial-up access, one is a mobile satellite system, and the other is setup for secure RAS for state side dialing.
How does it work when I dial from a PSTN line to a ISDN line, think along the lines of a direct PC to PC connection (in our case we are using secure phones to encrypt the data through a serial interface on the phone and shooting it out the phone line)
What, if any kind of problems would I run into dialing PSTN to ISDN?
Let me know if you need more info on the setup.
