I had a big problem as a similar situation.  Polycom phones would wig out if 
caller id info came in wrong or there was an error (which looking at a few CLI's 
with analog zap, happens fairly often).  The polycoms would ring, but would not 
pick up the call in this case. Not if you picked up the handset and not if you 
hit the Answer soft key either.  Took me about a month to track it down and 
finally was able to reproduce by performing an originate AMI command on local 
channel without setting caller ID.

Anyway, I finally just added a conditional to the entry point of my dialplan 
(after property answer(), Wait(), etc) that looked at the caller id and if they 
were blank, I set to something like 555-555-555/UNKNOWN and the problem went away.

In this case, sometimes the zap channels would get hung up as well and required 
a restart now.
