Call progress tones VVX411 and 500

I am trying to set up UK dial tone on the above phones as detailed in the following link :-


On the VVX500 the UK dial tone works as expected but on the VVX411 the dial tone sounds more like a number unobtainable tone, the sections used in the VVX500 provisioning file are the same as the ones used in the provisioning file for the VVX411.


is there something obvious like that possibly custom dialling tone isn’t an option on the VVX411?

Hello @Telecomuser ,


Welcome to the Poly Community.

Good info for the volunteer here would be the currently used software version and if you have yet compared a backup from both phones to check that the same parameters are being used.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
