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 
Auto answer is probably disabled.
voIpProt.SIP.alertInfo.1.class=“4”
voIpProt.SIP.alertInfo.1.value=“Auto Answer”
voIpProt.SIP.requestValidation.1.method=“source”
voIpProt.SIP.requestValidation.1.request=“INVITE”
The “Auto Answer” value in the phone’s config file worked for me
I just added this towards the end of the file
