[asterisk-users] PRI Problems

[Rob Schall]

Hey Everyone,

So this is a problem I've been having for sometime now. I sent a few
messages to the list with no luck.

The problem is that when people dial into the Asterisk system using DID
numbers, it works the first time or 2, then I get busy signals.
A friend recommended I clear out the zapata and zaptel, start over, and
recreate my wanpipe stuff. He thought the problem was with the spans
themselves.

However, when I use the following information, and restart wanrouter, I
get an error.
