[Spce-user] Generate Ringback tone and 183 when receiving 180 ?

[Lorenzo Mangani]

Hi Walter,

The ringing tone towards the user should be locally generated by the
UA/device receiving a 180 and involves no early-media.
You should check what's up with your clients being unable to do so as a
first step troubleshooting this - if its a soft-client it might be simply
missing its local audio files, etc.

Kind Regards,

Lorenzo Mangani
