Hi I have a phone that needs an external Ringer, they already have an analogue bell connected from an old ISDN phone system so I want to reuse that. I have done this before by using a Cisco SPA112 and it worked perfectly using the quick setup, this was using a PBX on the premise so was local to the SPA112. I am trying to set it up using a hosted PBX and I can't get it to connect, do you have any ideas? I have entered the FQDN & extensions user ID and password into the quick setup. Any help would be appreciated.
