Cisco 7960 Ring Tone / Huntgroup Melody


Recommended Posts

I have noticed that if you specify a specific ring tone on a Cisco 7960 (other than the default chirp) it will not be played when calling the extension from the inside, or outside of the office. However if the phone is part of a hunt group where the ring melody is set to none, then the ring tone you selected on the phone will play. I am guessing that the PBXnSIP is sending a specific ring melody to the phone and overriding the user's selection. Is there a way to stop the PBXnSIP from sending a specific melody to the phone without needing to have it ring through a hunt group that is specifically set not to send one?

Probably the Cisco did not like the http in the alert info. Can you give the attached ringback.xml a try? You need to restart the service for that or load it through the special web interface page (Reload Configuration Files in admin/configuration).
