Re: [asterisk-users] get SIP extension status without calling it

Suppose that the user agent is not a softphone but a
gateway such as the Grandstream GXW-4008 ATA.
One of the FXS-port-connected phones of the gateway
has DND turned on.
IF I send an OPTIONS request then the UA always
answers with a 200 ok even if the extension is
actually busy.

In this particular case, how does one get the status
of an extension "behind a user agent/gateway"? (am I
writing the sip url correctly in the sofia-sip options
utility below?)

("database show dnd" does not yield anything)

# ./options -1 -a sip:4064@192.168.250.1
