[Asterisk-Users] Outbound E&M?

[mfarver at ticom.com]

I've got a new setup (different building) where Asterisk is sitting
between the PBX and phone company on a E&M T1 line.

Mitel PBX <-> Asterisk <-> Phone company

Inbound works.  Asterisk gets the in-band digits from the phone company
and hands the call off to the Mitel just fine.

Outbound is weird.  Asterisk seems to expect that the mitel will send
routing information (out-of-band, I assume) when the line goes off hook. 
The mitel doesn't send anything, so the call drops into the s extension. 
After waiting a few seconds, the mitel sends the number in-band as DTMF.  
I tried putting DISA with no password into the s extension, hoping it
would trap the DTMF and hand it off but instead DISA exits non-zero and
never transfers control to the local context.  Without Asterisk in-betwen
all works fine.  Any ideas.. or is there a better way to do this?
