I guess that the softphone should be answering with a
2xx code followed by a status description?
So I tried with the INVITE method and set DND on the
SIP extension:

# ./options -1 --all --method INVITE
sip:10.215.147.240
SIP/2.0 486 Busy Here
Via: SIP/2.0/UDP
10.215.144.27:38098;branch=z9hG4bK5Z3BS8F737t0e;received=10.215.144.27
From: <sip:10.215.144.27>;tag=590Z1ND8B6XpN

CSeq: 92182952 INVITE
Content-Length: 0
Server: SJphone/1.65.377a (SJ Labs)

The above would suit me fine because I get a "486 Busy
Here" response.
However, if DND is off then I get:

# ./options -1 --all --method INVITE
sip:10.215.147.240
SIP/2.0 180 Ringing

and the SIP extension actually "rings", as
expected.(but this is undesireable)

Now, does someone know another way to get the status
(ie. does it accept calls or not?) without making the
extension "ring"?

Thanks
