Android ePos caller ID app help!

Hi basically I have a new ePos system at my shop, they have a feature where it automatically inputs the callers number into the system to bring up their ‘profile’ from previous orders they’ve made. However their caller ID app runs from Android phones and obviously we use landline phones. I just wondered if anyone knows a way to have the android app triggered by a landline phone without having to do call forwarding? The invoxia VoiceBridge would have been perfect but of course they have discontinued it. I just want a cell phone to receive a call alongside the landline phone. Thanks!
