First up, the best you are going to do with a RAS - modem to modem, is 33K. You won't see any higher and will possibly be lower. The "56K" speeds, if you even get those, are due to the fancy modems used by ISPs, but yours are straight modems and will only return you 33K at best.

It doesn't take a lot to drop the speed to 28 or 26K, a bit of line noise or PABX buzz and you are history.

It may be a good thing to go VPN, as that will allow you to benefit from the higher speed connection through the ISP, but with the higher overheads of VPN versus direct dial, you may find it no quicker. I have seen a person get 46K Internet connection at a particular phone point, then move 2Km away and get 24K, and yet the phone line sounded fine. So all those variables come into play.

However, given that they are all getting slower than normal speeds, it is probably at your end of the line, and possibly in your phone PABX or whatever you are using.

Try setting up a RAS on a machine at another location - like your home, and get them to dial into that and see what speeds they are achieving there.

Sorry I can't be of more assistance.
