[SR-Users] Resolved: JsSIP:UA Request-URI does not point to us

[Xuo Guoto]

Did some more digging into the source code of JsSIP. The condition that triggers the error message is:
https://github.com/versatica/JsSIP/blob/3ab1fa7c8e09231c41ca21657bf962323906d5fe/lib/UA.js#L560
  /**
   * Request reception
   */
  receiveRequest(request)
  {
    const method = request.method;

    // Check that request URI points to us.
    if (request.ruri.user !== this._configuration.uri.user &&
        request.ruri.user !== this._contact.uri.user)
    {
      logger.debug('Request-URI does not point to us');
      if (request.method !== JsSIP_C.ACK)
      {
        request.reply_sl(404);
      }

      return;
    }

If I understand correctly if ruri.user is neither user in config or user in contact the request gets rejected.

R-URI is:
ACK sip:stg-cqd0r2-10020005 at erx-staging-q01.mydomain.com;gr=urn:uuid:b8a691ff-f678-4866-8cf0-780d670e7e33 SIP/2.0

The SIP URI configured in tryjsip is sip:Stg-CQD0r2-10020005 at erx-staging-q01.mydomain.com

This does not match, but if I change the SIP URI to
sip:stg-cqd0r2-10020005 at erx-staging-q01.mydomain.com (all small case) it works fine. I am not sure if this is a bug or violates the any RFC
