Hi,
Sorry, but the callee type detection functionality can only be toggled on and off through Plum Support.
To enable/disable callee type detection, you can send an e-mail to support@plumvoice.com with your 8-digit customer ID in the subject line asking for this to be done. Your 8-digit customer ID can be found in your support contract with Plum.
Regards,
Plum Support
