[Asterisk-Users] Asterisk calls back after phone call

[James Doherty]

I'm using a Grandstream IP phone to call someone through our asterisk
pbx. The PBX is running "Asterisk 1.0.3-BRIstuffed-0.2.0-RC3" and uses
2x ZAP-HFC cards.

When I call someone, if the call isn't answered and then I hang up, I
get "487" coming up on the grandstream phone. If I pick up the receiver
again and then hang up, the PBX starts calling me back and when I pickup
and listen, there is silence.

Using debug mode doesn't indicate anything suspicious:

-- Executing Dial("SIP/james-d986", "Zap/g1/8171208") in new stack
-- Called g1/8171208
-- Zap/1-1 is making progress passing it to SIP/james-d986
-- Hungup 'Zap/1-1'
== Spawn extension (default, 8171208, 1) exited non-zero on
'SIP/james-d986'

The callback happens after the last line above. I don't believe this was
happening before I upgraded to 1.0.3 (I was previously running a pre-1.0
cvs build from about 2 months before asterisk 1.0 was released).

Has anyone experienced this behaviour before?
