Did some more digging into the source code of JsSIP. The condition that triggers the error
message is:
https://github.com/versatica/JsSIP/blob/3ab1fa7c8e09231c41ca21657bf96232390…
/**
* 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@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@erx-staging-q01.mydomain.com
This does not match, but if I change the SIP URI to
sip:stg-cqd0r2-10020005@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
Sent with ProtonMail secure email.
