Secure VoIP desktop apps for Windows and Mac

You can answer and make calls on your ASH NET number from a computer with a headset. The desktop apps use the same login as the mobile app: your phone number and SIP password.

Setting up

  1. Install the app and open it. Windows may ask you to confirm the download – the installers are published by the app’s developer for our platform.
  2. Enter your phone number (digits only) and SIP password. If the app asks for a server or domain, use sip2.ashnet.co.nz (port 5060).
  3. Allow the app through Windows Firewall / macOS privacy prompts and choose your headset under audio settings.
  4. Dial *55 to reach your voicemail and confirm audio works both ways.

Using several devices on one number (desk phone + computer + mobile)? Turn on the shared-line feature and log each extra device in with a -1, -2 … suffix – see Simultaneous ring and shared line.

All downloads are also listed on our Secure VoIP app page.
