[oclug] Asterisk question: dealing with a SIP phone that's left off the hook?

[Rob Young]

Hi there,

I'm trying to find out how to fix a problem I'm having with my
asterisk home setup, maybe some here can help.

I have one grandstream ATA (286 HT) set up as a SIP client for all incoming
and outcoming calls for my setup. I noticed recently, if one of
the analog phones connected to the ATA is left off of the hook, it
will automatically pick up an incoming call. This isn't good, because
if someone calls the house, they'll get a phone with no one on it! :)

I would like my set up handle this better, perhaps to instead start
beeping or hang up the connection? Is there a standard way to set this
up? Is this usually configured in the extensions.conf file, or on the
ATA? I have looked through the info on voip-info for tips on how to
deal with this, but haven't found anything to solve my problem.

Thanks,
Robert Young

Ps: are there any active asterisk forums I should be asking this
question?  The voip-info forums seem to be very dead.
