What does "destination-pattern .T" mean? I'm not familiar with what
".T" would match. I would suggest using a more specific pattern that
you expect to be coming down the line.

Doesn't see any traffic when? When the asterisk tries to call the
Cisco? That would suggest you have a sip.conf misconfiguration on
asterisk.

No traffic when the Cisco tries to call the asterisk? That could be
for a number of reasons. I would suggest your destination-pattern
could be bad, since I don't know what that syntax means. If an E1
works like a PRI T1, when you dial in, a DNIS is getting pushed to the
Cisco, and that's what you should match your destination-pattern on.
Regardless, SOMETHING is getting pushed down the wire when an E1 call
comes in, and you're getting a busy because Cisco has no matching
dial-peers.

Finally, it's rather embarrassing that you're asking this from a
'network operations center' email address. How about using a personal
email address with your real name?
