Trying to make paging work with Polycom phones, which unlike Linksys doesn't just work out of the box.
I ran across this Polycom 'Technical Bulletin 43565' which outlines how you need to edit the asterisk extensions.conf file and add a line like
exten => 9027,1,SIPAddHeader (Alert-Info: info=intercom)
Could anybody advise if this on the right track to make paging work for Polycom phones, or if there's some other way to do this in the GUI.
Don't want to break anything anywhere in the MTE...v6
