[cisco-voip] Emulating the PSTN

[Kris Seraphine]

You can use a router as a ISDN network side connection and make T1 crossover
cables so you can network 2 or more routers.  For my ccie lab I used a
router with two VWIC-MFT-T1 cards and a VWIC-MFT-E1 card.  I then used
various other routers with VWICs for the ISDN user side.  This has the added
benefit of making you configure the call routing on the network switch.

If you have access to non-production cisco gear this is a good way to go.
