How did your dialplan change.  When do the hangups occur?  Is there a pattern?

I have done a few E&M wink setups with no issues other than getting
the configs and dialplan right.

Personally, I would ream your provider rep and demand that your
situation be escalated to the top.  If they don't agree, go over their
head, I always get an escalation form with contacts for each
escalation level.  Obviously, when thing are straightened out, make it
a point be very thankful to everyone and CC them with what a great job
they did.
