Voice IP Update

On January 23, 2024, Twilio transitioned to using the media IPs and port ranges for SIP calls in all regions to 168.86.128.0/18 and expand the UDP port range to 10000-60000. Old IP and port ranges will no longer accept or send traffic after this date. Information on how to check if your setup with the new IPs is correct can be found here.

Region-specific IPs

Please review Voice Media Servers Connectivity Requirements to review IPs to allowlist. We suggest allowing all the IPs listed in the link above unless you decide to pin calls to a given region.

Other

If your router includes SIP Application Level Gateway (ALG) function or Stateful Packet Inspection (SPI), disable both these functions.

User analytics

Used for product analytics. It acts as a single interface for product errors. With other analytics destinations allowed, it helps us understand how customers are using Gladly and we can improve. Necessary for analytics; however, it is useless by itself.

Check Firewall

After completing the above requirements, we recommend checking your firewall against a tool. To check your overall firewall and port configuration, we recommend:

Allow Inbound Traffic

Allow Email From

We send emails from three dedicated IP addresses listed below. In case you filter on sender IP addresses, you will need to allow emails from your domain to be received from these IP addresses:

  • 143.55.235.42

  • 192.237.158.181

  • 198.244.49.44

Allow emails from @gladly.com domain, and we suggest allowing the email addresses listed below:

Verify Bandwidth

If you are using Gladly Voice over the web, you must have at least 100 kb/s per online voice Agent at any given time. For example, if you have 25 online voice Agents, you must have 2500 kb/s. See our infrastructure requirements for more information.

Network Testing

At the beginning of your implementation, we will ask you to test your network under the following scenarios to verify you are set up as needed:

  • Timing: Daily, for one week, at the beginning, middle, and end of your customer support hours.

  • Hardware: Must be tested using a customer support agent’s actual machine and setup (e.g., plugged into ethernet).

  • Network: Must be tested on the same network that agents use for their work.

To test your network, follow this link: https://networktest.twilio.com/. We are looking for you to pass only the following tests:

  • UDP: Makes sure you can communicate voice packets over the internet

  • TURN TCP: Allows Gladly voice to communicate back-and-forth with you over webRTC

  • TURN UDP: Allows Gladly voice to communicate back-and-forth with you over webRTC

  • Bandwidth: Tests how much available bandwidth there is for webRTC communication

  • Test Call: Tests that you can do a test call with the Gladly Voice provider

Upon completion of each test run:

  1. Take a screenshot of your output.

  2. Send it to your implementation team.
