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

[Vieri]

I also tried:

# ./options -1 -a sip:4064 at 192.168.250.1:5072

but still received a

SIP/2.0 200 OK
Via: SIP/2.0/UDP
10.215.144.27:38102;branch=z9hG4bKFB4rQrr5aXp9H

Call-ID: 83259dd2-1b9e-122b-10a3-00c09f10e472
CSeq: 92189848 OPTIONS
Supported: replaces, path, timer
User-Agent: Grandstream GXW-4008  V1.2A 1.0.0.67
Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE,
NOTIFY, INFO, REFER, UPDATE
Content-Length: 0

Is Grandstream GXW-4008 not 100% SIP compliant, too?
