Re: [OpenSIPS-Users] Problem: Registration Proxy with WebRTC

[Dragomir Haralambiev]

Here is answer from JsSIP but I do not know how to setup Opensips:


=== answer ===
The error log does tell you what is happening:

```
JsSIP | SANITY CHECK | Via host in the response does not match UA Via host
value. Dropping the respons
```

Have a look at the chapter 18.1.2 from RFC 3261:

```

18.1.2 Receiving Responses

   When a response is received, the client transport examines the top
   Via header field value.  If the value of the "sent-by" parameter in
   that header field value does not correspond to a value that the
   client transport is configured to insert into requests, the response
   MUST be silently discarded.

```

The "sent-by" parameter in the response has been altered from the one sent
out from JsSIP. Your server is manipulating such a value and that makes the
response to be discardes as per RFC 3261.

Re: [OpenSIPS-Users] Problem: Registration Proxy with WebRTC

[Bogdan-Andrei Iancu]

Hi Dragomir,

Do you have any idea if the "Via sent-by" reported by SIP.JS is actually 
about the "received" parameter returned in VIA by OpenSIPS ?
