Telephone: An elegant SIP softphone for the Mac

If you’ve got a Mac and an Asterisk-based phone system, I highly recommend you check out Telephone, an open source OS X “softphone” with the following design philosophy:

I don’t know why they think you should like a mobile phone interface on your computer.

Which is, I assume, a shot over the bow of softphones like X-Lite. And, true to those words, here’s the simple UI:

I’ve been trying Telephone out for a few days on long conference calls. Other than not being able to figure out “flash the switch hook” to be able to transfer calls (it’s a feature request), it’s performed flawlessly, and has enabled me to switch away from Skype to live the headset dream.

Thanks for the post! This app is sweet! It is so dang stable compared to all the other options out there — i/c xlite, isoftphone, etc……. Love listening to itunes and it muting when a call comes in, and then starting up again on completion! Needs to change the name of the app so more search hits would catch it — maybe i-tel? Thanks again — if not for your post — i would have missed it.

Recent versions of Telephone include “Transfer” capabilities: just press “T” during a call.
