[jitsi-dev] implementing support for sipwitch


#1

Dear Jitsi devels

In discussions pertaining to SIP vs Skype it is sometimes suggested that Skype's peer-to-peer connectivity is much better than SIP. Recently I've been introduced to sipwitch [1][2], and although I didn't quite understand all the technical details, it seems to allow clients to use a Skype-like network.

  GNU SIP Witch is a secure peer-to-peer VoIP server. Calls can be made
  even behind NAT firewalls, and without needing a service provider. SIP
  Witch can be used on the desktop to create bottom-up secure calling
  networks as a free software alternative to Skype. SIP Witch can also
  be used as a stand-alone SIP-based office telephone server, or to
  create secure VoIP networks for an existing IP-PBX such as Asterisk,
  FreeSWITCH, or Yate.

Would this make any sense for Jitsi? Perhaps as part of a GSoC project? Cheers
Liviu

Liviu,

as far as I know we do not need to anything special in Jitsi to
work with Sipwitch. Actually Sipwitch acts as a normal SIP proxy/registrar
and is thus should be compatible with Jitsi. Sipwitch handles the
SIP signaling only and not the audio/video channels. Asterix for
example mostly also deals with audio/video which often prevents
secure encrypted calls. AFAIK with Sipwitch you can build a mesh of
SIP proxy that can communinate and route SIP requests inside
the mesh and to the connected/registered clients.

Best regards,
Werner
