Set firewall for direct media delivery

Two specific policies must be put in place on your network's firewall to ensure you receive all audio on Flowroute calls:

  1.  SIP signaling (call control): Allow UDP and TCP traffic over port 5060[1] from the following server IP addresses:

    Point of Presence (PoP)        SIP Proxy IP Range
    ------ ------ UNITED STATES ------
    US-East-NJ (retiring in Aug 2022)
    ------ ------ ASIA PACIFIC ------

    before June 14 2022:

    starting June 14 2022:

    ------ ------ EMEA ------
    EU-West-AMS (retiring in June 2022)
    ------ ------ LATAM ------
  2.  RTP media (call audio): To reduce latency, Flowroute uses Direct Media Delivery. To receive Direct Media, allow UDP packets from any source IP address with a destination port within your system's RTP public media port range.[2]
