[Asterisk-Users] Is there a product to simulate a PRI trunk?

[Chris A. Icide]

You should note that while this "works" technically, it won't catch any 
issues that you may experience when connecting to other PRI switches.

In other words, two asterisk servers connected back to back with a T1 
cross-over cable won't tell you that Asterisk's NFAS code doesn't work with 
Lucent 5ESS switches, or that Sangoma's code pre-firmware v1.1 and 
pre-driver beta6 versions won't bring up the D channels when connected with 
certain switches.  Everything will work between two asterisk boxes perfectly.
