[END OF LIFE - ABANDONED - DISMISSED] DSS VoIP Notifier

I just tried on another instance of HA which is located on the 192.168 network, and there, it connects. I can call the extension.
But the call doesn’t work :

Current call id=0 to sip:[email protected]:5060 [CALLING]

Seems to be related to transport. That’s with “no-tcp” flag. Without it, I get another error message :
