Here’s an admission of sorts. I quite admire Dave Michels’ friend Colin Berkshire. He’s a consistent source of both wit and wisdom. For example, today he describes his somewhat unusual use of a Grandstream GXP2160 IP Telephone in My Line-less Desk Phone.
Not to spoil the punch line, but the phone can be paired to a mobile phone via Bluetooth, making it effectively a great handset for his iPhone. So it’s genuinely useful even without having a SIP line registered.
Other companies like Mocet & Invoxia (review) offer similar capability in dedicated function devices, but these cost considerably more than the GXP-2160, which is currently listed on Amazon for just $99.
I wish I could do the same with my Polycom VVX-600!
