Description

What Voxter IP addresses and ports should I whitelist on our corporate firewall?

 

Resolution

  1. The easiest option is to whitelist Voxter's Global Network: 74.114.208.0/21
  2. In conjunction with the Voxter global IP network, if you need to get more specific, then you will need to (at a minimum) open the following UDP ports for registration and phone calls to function:
    • SIP Signalling Ports: UDP 5060 & 7000
    • RTP Audio Port Range: UDP 16384 - 32768
    • Provisioning of phones: TCP 80 & 443 outbound
    • DNS & NTP: UDP 53 & 123 outbound
  3. Note: Additional IP's and ports may be required depending on additional functionality being utilized (such as Voxter Developer APIs). If this is the case, please contact Voxter Support
