How to Use VoIP Calling with Doximity Dialer

About VoIP Calling

Doximity Dialer supports VoIP (Voice over Internet Protocol), which allows you to place Dialer Voice calls using an internet connection.

With VoIP Calling enabled, you can:

  • Place Dialer Voice calls over WiFi or cellular data
  • Display your selected Caller ID to patients
  • Switch an active Dialer Voice call to a Dialer Video call

For both VoIP and non-VoIP calls, your patient will receive a standard phone call from your selected caller ID.

NOTE: To place Dialer VoIP calls over WiFi, WiFi Calling must be enabled in your device settings.

If WiFi Calling is not enabled, VoIP calls will use cellular data. When WiFi Calling is enabled, Dialer will use WiFi when your device is connected to a WiFi network and cellular data when WiFi is unavailable

  1. Tap Switch to Video.
  2. Dialer will send the patient a video link by text message.
  3. Ask the patient to open the link and allow camera and microphone access.

  4. Once the patient connects to the video session, the voice call will end automatically, and the video call will begin.

Common Questions

What does my patient see when I use VoIP calling?

Your patient will receive a standard phone call from the Caller ID you selected in Dialer.

Does VoIP Calling use cellular data?

Yes, if you are not connected to WiFi.

VoIP calls use your cellular data connection instead of your cellular plan's voice minutes. An average five-minute call uses approximately 6 MB of cellular data.

To avoid using cellular data, connect to WiFi before placing your call.

Should I use WiFi or cellular data?

We recommend using a strong WiFi connection whenever possible for the best call quality.

If WiFi is unavailable, VoIP Calling can also use your cellular data connection.

How can I improve my call quality?

For the best call experience:

  • Connect to a strong and stable WiFi network.
  • If you are using cellular data, make sure your device has a strong signal.
  • Consider using headphones or a headset to reduce background noise.
  • Avoid switching between WiFi and cellular networks during the call when possible.

Can I turn VoIP Calling off?

Yes. Turn off Use Internet to Place Calls from your Dialer voice settings.

You can turn this setting back on at any time.

Does this change how Dialer Video works?

No. Dialer Video continues to operate separately from Dialer voice calls.

VoIP Calling simply gives you the additional option to move from an active voice call into a video call.

Information for IT Teams

For additional network requirements and configuration recommendations, see How to Prepare Your Network for Doximity Dialer Video (for IT Professionals).

IT teams can also review the following:

  • Prioritize VoIP traffic using Quality of Service (QoS) when supported by your network.
  • Check whether your internet service provider is shaping or throttling VoIP traffic.
    • Contact your ISP. Some service providers may prioritize your traffic over others and/or improve the contention ratio. Ask if they are shaping or throttling your connection specifically for VoIP traffic. Ask them if they can prioritize VoIP traffic and/or offer a contract that is unshaped and unthrottled.
  • Investigate packet loss or network congestion if users experience inconsistent call quality.
    • Forcing an alternative route, via a DNS proxy or similar mechanism may improve transport reliability.
  • VPN connections can add latency and jitter. Consider excluding Dialer VoIP traffic from your VPN when troubleshooting call-quality issues.
