Network Requirements for Dialpad Meetings

Network configuration is vital for video calls! Dialpad Meetings has a few requirements and recommendations to help keep your clients happy, and your presentations clear and visible to all participants, regardless of their joining location. 

Let's dive into the details of network infrastructure for Dialpad Meetings. 

Ports for Dialpad Meetings

Specific ports and protocols must be enabled to use Dialpad Meetings.

Stateful firewalls (not the same as stateful packet inspection!) are recommended for Dialpad Meetings deployments. Stateful firewalls do not need inbound port configurations as they automatically open as a reply to the outbound traffic.

FQDNs for Dialpad Meetings

Routing to a Fully Qualified Domain Name (FQDN), allows modern cloud networks flexibility for routing, security, system maintenance and remote device management.

Dialpad recommends allowing traffic to and from each of the following FQDNs:

• dialpad.com
• www.obitalk.com
• www1.obitalk.com
• prov.obitalk.com
• devpfs.obitalk.com
• storage.googleapis.com
• ubervoice.ubervoip.net
• turn.ubervoip.net
• stun.l.google.com
• uvwss.ubervoip.net
• legacy.dialpad.com
• dialpadcdn.com
• static.dialpadcdn.com
• prov*.dialpad.com
• google-public-dns-a.google.com
• google-public-dns-b.google.com
• *pusher.com
• *googleusercontent.com

Firewalls for Dialpad Meetings

We also require that the following features be turned off for Dialpad traffic (as they can interfere with the service). Please contact our Support Team if you are unable to turn off these features:

• SIP-ALG
• Deep Packet Inspection (DPI)
• Stateful Packet Inspection (SPI)

Test your meeting configuration

Before joining a meeting, we recommend testing your setup. 

Test your setup anytime from https://videotest.dialpad.com/ 

You'll also find the test link in email and Google Calendar invitations.
Joining a meeting if ports are blocked

When ports (webRTC or firewalls) are blocked, you can join a meeting as an audio participant.  You won’t have full meeting permissions, but you can still view screenshares.

Dial-Out to join a meeting

If you experience a network connection issue when trying to join a meeting (or even during a meeting), you’ll be prompted to check your network settings, and given the Dial-Out option. Dial the number listed on the screen, or enter your phone number so that we can call you.

Limited connection screenshare

If a user is connected to the Internet and encounters a blocked WebRTC or firewall port, they will not be able to view screenshares initially. 

Dialpad provides a secondary screenshare option — if your connection is blocked, all you need to do is select View screenshare from the pop-up message.
