[Asterisk-Users] PRI pass-through

[Jerry Jones]

This will not work. The PRI uses a single D channel for signalling.  
It can only go to one PBX, either * or legacy. Yes the cisco can map  
DS0 between the E1, but I believe you need the VWIC-MFT series to do  
so (may be wrong on that) but that will definately break the PRI.

Either run the PRI directly to the legacy as is and add another from  
legacy to *, or connect the PRI to * and add a second from * to legacy.

Good Luck
