The Secure VoIP app lets you make and receive calls on your ASH NET phone number from your mobile, anywhere you have internet. Calls to your number ring the app; calls you make show your ASH NET number.
Download
- iPhone / iPad: search the App Store for “Secure VoIP” or open this App Store link on your device.
- Android: search Google Play for “Secure VoIP” or open this Google Play link on your device.
An alternative app, the Basic Edition, is also available – see Secure VoIP Basic Edition. All apps for phones and computers are listed on our Secure VoIP app page.
Log in (iPhone)
- Open the app and tap Allow for notifications, photo library, camera and contacts. Without notifications the app cannot wake up for incoming calls.
- Enter your phone number (digits only, as shown in the VoIP portal) and your SIP password, then log in.
- On the dialler screen tap the three dots in the bottom-right corner, then the phone button on the left. This places a test call to your voicemail.
- Tap Allow when asked for microphone access. You are ready to make and receive calls.
Log in (Android)
- Open the app and tap Allow for notifications – without this we cannot wake the app for incoming calls.
- Enter your phone number and SIP password, then log in.
- Tap the three dots in the bottom-right corner, then the phone button on the left to place a test call to your voicemail. Allow microphone access if asked.
- The first time you open other screens (for example Contacts) you will be asked for more permissions – always tap Allow so every part of the app works.
Your login is your phone number and the SIP password we emailed you – not the VoIP portal password. If you have lost it, contact us and we will reset it.
Battery settings (Android)
If incoming calls stop ringing after a while, exclude the app from battery optimisation (Settings → Apps → Secure VoIP → Battery → Unrestricted) so Android does not put it to sleep.
Next: Blind transfers in the app · Attended transfers in the app · Voicemail.
