Currently, I utilize two phones. Both of these phones serve a role and purpose. The first phones are two Ooma HD3 handsets. These are DECT phones that works with the Ooma Telo ATA. These are essentially my home phones which I use for some outgoing calls, and receiving incoming calls.
The second phone is an iPhone 12 Pro (128GB). This phone is my primary phone which most of my calls are made through this phone. In addition, I have a SIP client installed which I use to receive SIP calls, or calls to the phone numbers associated with my SIP accounts.
