Hi - I live in an apartment building where the intercom connects to my iPhone. Pretty standard. However, the intercom can only be connected to one phone number. This means that if I am not home my partner cannot let anyone in because only my device rings. I am trying to figure out an automation for my iPhone to recognize the incoming intercom call (it does have a unique phone number) and to make both of our devices ring simultaneously, so either one of us could answer the intercom.
If anyone has a shortcut/automation for this, or could point me in the right direction I would really appreciate the help. Thanks - Stephen
