Hello,
 
Having 1 boxes with SIP service Box A: ip a.b.c.d with sip at udp 5060 and a  NMS machine with ip x.y.z.t
 
I am looking to monitor the SIP service via OPTION sent from NMS (x.y.z.t) to the box A (no user defined on the box)
 
Any one to help how to write the OPTION request using sipsak
 
I tried this way but no success
 
sipsak -f option -s sip:a.b.c.d   (I don't know if we have to set the udp port with sipsak)
 

On file option I have:

 

OPTIONS sip:a.b.c.d:5060 SIP/2.0

Max-Forwards: 70

To: <sip:ping@a.b.c.d:5080>

From: NMS <sip:x.y.z.t>

Call-ID: 83185420572

CSeq: 8764 OPTIONS

Allow: ACK,CANCEL

Accept: application/sdp
