I suspect if you enabled the tport_log sofia logging you would have seen it trying to send and failing for some reason

Hi, All!

Thank All!

I apologize for my negligence and  inadvertence.

Because a bare-bones gateway was setup for outbound calls with no username/pass and without registration I omitted an important parameter
<param name="register-transport" value="tls"/>

Now, with this parameter, the situation has returned to normal.

A lot of thanks to All!
