Domain of URI works ok with sip.pstnhub.microsoft.com. Domain of From works ok with localhost. Domain of To works ok with sip.pstnhub.microsoft.com. Those are not important.
It is important that you have the right Contact: Contact: <sip:[YOUR_DOMAIN]:[YOUR_PORT];transport=tls> If your Contact is right, then something is misconfigured on MS side. Check that you have the right licences, the right port, that there are no typos ... Enable debug logs and check that connection is successful and ensure that all the certs are valid and set to be verified. -ovidiu On Mon, Apr 15, 2024 at 1:38 PM Tyler Preder via sr-users <sr-users@lists.kamailio.org> wrote: > > We set the URI domain in the OPTIONS to match our system’s fqdn.
