I have 3CX v11 and some SPA504G and SPA514G phones and I am trying to get the paging/intercom feature to work. When I dial *9 and the extension (i.e. *9200) the phone wants me to set a call forward. When I disable the call forward feature in the phone, it then just gives me an invalid number error after only dialing *92. The built in paging feature in the SPA504G is set as *96. When I use this (i.e. *96200), the other extension does not auto answer to the speaker phone like I'm hoping and instead rings and rings as if I simply dialed their extension, despite auto answer being enabled in the phone preferences. Any ideas?
