Cisco SPA504G - Outgoing calls do not give a ringback tone

[LeighWardle]

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

AVM think SPA-500 series doesn't fully support HD codec g.722 and they recommend to deactivate this codec on the phone.

Eureka! That fixed it for me!
(Lucky – I was going to send the Cisco back tomorrow).
