Today i move our central server to 1.2.7.1 , and im having some issues
with SPA Phones and RinbackTone. Without r option, it also happens. Is
having anyone this issue? I think it has not been changed anything

Confirm you have /etc/asterisk/indications.conf Not having it can cause
ringback issues in some
