[Asterisk-Users] PRI calls to Automated Attendants Dropped

Sounds similar to a problem I've seen with a slightly different setup....
Calls to certain AA/PBXs were not passing progress information beyond 10
seconds into the call. Can you check your logs for the exact amount of time
after the setup that the call gets dropped? I'm guessing you'll see 10 or 11
seconds for most calls.
The work-around is to make the asterisk box doing the relaying Answer() the
calls before doing the outbound Dial().
