Polycom VVX 410 and paging function (*80) not working

I have been pulling my hair out trying to get the paging function to work on a Polycom VVX410 Media phone. Does anyone have any advise for me?
I cant do it to an individual phone or to a group. Do I need to change something in the Config files to get it to work? I am using the OSS deployment tool in Freepbx to config my phones.

Thanks for your help.

I have been pulling my hair for days on this too, same phones and some soundpoints 550, not even the paging works :triumph::sob:

Auto answer is probably disabled.

voIpProt.SIP.alertInfo.1.value=“Auto Answer”

The “Auto Answer” value in the phone’s config file worked for me

I just added this towards the end of the file
