Yes the patch is there, we need to review it. Also Inaki sugested some tunings in the PATH module (to fully support websocket).
Thanks and regards,

If oversip uses Path extension OpenSIPS must support it.
1- Sending Path header values in 200 ok REGISTER response
2- Path header files syntax must confom to Route syntax
3- When look up the opensips must copies the stored path header fileds into Route header fileds - preloaded route.
Reference: RFC 3327
Here i think adding one Route header pointing to OverSIP (second Path URI) is enough in simple case (UA ---- OverSIP--- OpenSIPS).
OverSIP removes the Route header and route the request based on RURI (first Path URI).
OpenSIPs support this http://www.opensips.org/html/docs/modules/devel/registrar.html#id248705
flag "px" (path support) of save function in Registrar module.
So still parsing VIA header is required to add WS and WSS. I think this patch is already posted.

Right. As Saul pointed out, this scenario (which is a pure RFC 5626
"Outbound" scenario with a Edge Proxy in front of the
- Path support in OpenSIPS for storing the Path URI(s). Note: It's
important to increase the "path" column size in the location table.
The current value is to small and cannot store two URI's (OverSIP adds
double Path headers).
- OpenSIPS should improve the parser of the Via transport field since
currently it only accepts UDP, TCP, TLS and SCTP. It should also
accept WS and WSS, but better if it accepts any token (as the RFC 3261
BNF grammar states). Otherwise OpenSIPS will discard SIP requests
coming from OverSIP (since the non top Via header, that created by the
SIP WebSocket client, has "WS" as transport protocol).
And nothing else at all, but the above two points are important.
