[Asterisk-Users] Grandstream Won't hangup like Polycom 600 will

[George Burt]

I have been experimenting with GXP-2000 Grandstream.

When I do this:

Grandstream > Asterisk > Polycom600
  then  Hangup the Grandstream, the Polycom hangs up and is ready for the
next call

Polycom>Asterisk>Grandstream
  then Hangup the Polycom, the Grandstream plays a busy signal.

I believe the firmware for the GXP-2000 is substantially the same as the
BugetTone.

Why is this important to me?

I have turned on "Auto Answer" on GXP-2000.  When someone wants to announce
a call, they dial the extension, talk, then hang up.  This is great if
someone is at the extension.  But if no one is there, the phone's
speakerphone will ring busy annoying everyone nearby.

Thanks,

George Burt
