asterisk users - Feb 2006 - Caller stuck in MoH after being answered by a phone that was forwarded to.

Can anyone shed some light on what happened?
Asterisk 1.2.1 with Zaptel 1.2.1

Here is what I know happened:
A call came into our main number and was answered 
Asterisk set the monitor CALLFILENAME and then started monitor.
The call was directed to a context called "open" where all calls go
during business hours.
The dial plan has a Answer() again, and then played a message (custom/1)

The next dial plan was for a Dial SIP/221&SIP/222 statement to dial our
reception phones.
One of the Receptions phones was forwarded because they were out on
lunch.
Extension 222 was forwarded to 249 who answered the call (Polycom 501)
249 Answered the call and then transferred to another users phone (223).

The phone (223) rang once and then stopped ringing.
The user on Zap/1-1 was stuck in MOH until he hung up.
