We have run into an issue with Polycom VVX phones auto-answering intercom calls while the device is on another call, and therefor in an active state. These particular phones are VVX500s running v4.1.8 firmware. I have tested on the 5.4 branch as well with the same result.
I have the below set up in their configs:
When you dial *0 + ext number, our server sends an invite to the extension number with an added Alert-Info header of 'intercom'. The issue is that if a user is currently on the phone with someone and another user intercoms them, their current active call is placed on hold, and the intercom call is immeditiately answered. I did some digging in the admin guide, but could not find a parameter to negate this behavior. Can you point me in the right direction?
welcome back to the Polycom Community.
Not looking to deep into this I assume it is working as designed especially using multiple different versions or we would have already a bug filed on this.
To change this you would need to raise a feature request as described in the FAQ:

Resolution: Please check => here <=
Maybe time to replace the server controlled "Intercom" with the phones PTT feature as this would consider if a user is busy.

I really like the PTT and Paging features that Polycom offers, but some customers complain because it's too many steps to page. You have to create the groups (which I can do on our provisioning server), but I have to create one for each extension. Then they have to push the PTT, select the user, then PTT. Additionally, the receiver can't just answer, they then have to push the button to answer the incoming message. It's not something my customers are used to :/
Can you confirm that this barge-in with auto-answer is normal operation of the device, so I can at least forward that back to my customer?
