Hi all,
My hardware consists of a Fritz!Box 7270 with latest firmware, a network switch and a Cisco SPA504G handset (running latest firmware).
For the last few months, when I make calls I do not hear anything, there is no ringback tone - I only hear the voice when the remote site picks up the phone.
I used to hear the ringback tone with the same hardware and software setup - I haven't changed any configuration settings on the Fritz!Box 7270 or Cisco since everything was working fine.
All the hardware has been powered down and rebooted multiple times.
Regards,
Leigh
