[c-nsp] Frame relay over L2TP?

[Jim McBurnett]

Hello all,
I have been doing a little research into providers for A Frame relay implementation of VoIP.
This particular case is for a customer.

The customer insists a certain provider (I won't name them in public) is using L2TP to run the frame backbone.  And this backone is also the same infrastructure this provider runs their public Internet backbone on.

Having worked extensively with several of these large providers (MCI, Sprint, Level3, AT&T, etc) I find this a difficult 
Design to swallow. Am I naïve? Or is this just weird?

So I ask if any of you can truly tell me this is bogus, please let me know.

>From the customer side, they want to do VOIP, but if this is true then I have do think hard about the
Ramifications of what will happen with VOIP packets if they go from FRAME, L2TP, back to frame etc..

I would prefer to see offline comments. If you are the provider mentioned, I'll explain more.


Thanks,
Jim
