Telephone is a basic but reliable SIP softphone for macOS, available free from the Mac App Store. It is a good choice if you only need to make and take calls from your Mac.
- Install Telephone from the Mac App Store and open it.

Optional: switch to TLS
UDP is not encrypted and some firewalls interfere with it. If we have confirmed TLS settings for your account: open Telephone → Preferences, go to Accounts, untick Enable this account, open the Network tab and set SIP Transport to TLS, then tick Enable this account again. Email [email protected] first if you are unsure whether TLS is enabled for your line.
Under Sound choose your microphone and headset; untick Call waiting in General if you want second callers to hear busy while you are on a call. During a call, type digits on your keyboard to select auto-attendant menu options.
