Summary:                    Asterisk deadlocks with a SIP channel locked
Description: 
We run a complex application with calls originated via AMI Originate
command to Local channel. The local side of channel obtains an "agent" from
a queue, and the remote side is calling a customer via an outgoing SIP
trunk.

Very unfortunately, we had to cancel our upgrade to 1.8 and reverted the
only production server back to 1.6, mostly because of this issue. So
currently I have no setup that would be used in reproducing this problem
any more.

I think we should be able to try a fix, should it be a likely fix. So I
have two questions here:
1. Is it quite likely that DAHDI will work around the problem?
2. We have no telephony cards here, SIP only. Will DAHDI work without the
hardware? I have never considered it, so I know very little about it.
