How to set default audio path on a Polycom CCX 500 to headset?

[ssingh]

Hello,

I've been trying to setup the default audio path on a Poly CCX 500 to headset with no luck.

UC Software Version 7.1.0.8048

I've already tried the following options in the provisioning file but still no luck.

<headset
up.headsetMode="1"
up.audioMode="1"
se.destination="headset">
</headset>

Thanks,

ssingh
