Have you ever gotten this to work? I just went through this process and the phone will register and show online, but cannot call out. When the assigned DID to the phone is called, the call goes straight to the user's voicemail. I worked with RC Tier 2 support and they said the phones are not supported by RingCentral, so they will not work. Please let me know if this works for you and how your setup might differ from ours. Thank you.
