More on INVITEing phones to ring

This is a follow up on a previous post.

Apart from using a softphone, you can make use of svmap.py (part of SIPVicious tool suite) to reproduce the behavior:
./svmap.py -m INVITE 192.168.1.4 -p5061
Where 192.168.1.4 is the IP of the SIP phone and 5061 is the SIP port of the phone. For a ghost call effect, if you have a network with all SIP phones listening on port 5060, you can just run the following to get them to ring at the same time:
./svmap.py -m INVITE 192.168.1.1/24

Updated list of softphones tested and exhibiting this behavior:
  • WengoPhone **
  • X-lite release 1011b
  • SJPhone 1.65.377a
  • Ekiga 2.0.11 (beta)
  • Yate
