[asterisk-users] ISDN30 testing questions ...

[demuel at thephinix.org]

This is perhaps an architectural issue. I suppose you are planning to interface the "shining
asterisk-based VOIP box" with their "millenium old pabx"? What is the brand name of their old PABX
machine though?

In my humble opinion, your setup to connect two asterisk box peer to peer using two TE110p wont
work in this scenario. Why? How you would be able to make a test phone calls?
