Hi
I tried to figured out what you said and I made some tests but without
success.
Let me give you more info.
Scenario 1
Our issue is due to the Proxy Edge, indeed if we configuring the
Register (We have followed the websocket module documentation) to
directly manage the request from client everything works fine.
Browser Register
Client JsSIP Websocket
| |
| |
| ----------Register-----------> |
| <----------200 OK ----------- |
| |
| ----------Subscribe----------> |
| <----------200 OK ----------- |
| |
|<----------NOTIFY ----------- |
| |
Scenario 2
Instead when we configuring the proxy edge with websocket (we have
followed the *edge_websocket.cfg* example) and the register without
websocket we face the issue. As I wrote in my previous mail into the
log file of both proxy and register server we find "*Unresolvable
destination (478/SL*".
Browser Proxy Edge Register
Client JsSIP Websocket no websocket

| | |
| ----------Subscribe----------> | -----------Subscribe---------> |
| <----------200 OK ----------- | <----------200 OK ----------- |
| | |
| X<--- | <----------NOTIFY ----------- |
| | |
Could you please give more details to solve this issue.
Thanks a lot for your time.
Regards

In WebRTC (websocket) the contact header always has
invalid URI, so,
you MUST either use path module OR add contact alias for both REGISTER
and SUBSCRIBE requests otherwise any subsequent incoming SIP requests
such as INVITE and NOTIFY won't be routed to endpoint (SIP client).
See websocket module documentation which has an example configuration
script for handling these requests.
Kind regards,

Dear List
We have configured kamailio to work as a proxy edge and register.
As a proxy edge cfg file we have used the example
*edge_websocket.cfg.**
*
We are developing two different client the first one based on
*PJSIP* and the other one based *JsSIP*.
Client PJSIP (no websockets)
everything work perfectly, REGISTER, SUBSCRIBE, NOTIFY, PUBLISH,
MESSAGE, INVITE
Client JsSIP (with websockets)
The REGISTER, SUBSCRIBE works, the NOTIFY does not work.
In more in details we have:
Browser Proxy Edge
Register
Client JsSIP Websocket

As you can see the NOTIFY start from Register and reach the proxy,
beloe the Register log file and the sip messages.
Could somebody put me in the right direction.
Thanks
Bye
