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-West-OR us-west-or.sip.flowroute.com
    US-East-NJ us-east-nj.sip.flowroute.com
    US-East-VA us-east-va.sip.flowroute.com
    ------ ------ ASIA PACIFIC ------
    AP-East-HK ap-east-hk.sip.flowroute.com
    AP-Southeast-SIN ap-southeast-sin.sip.flowroute.com
    ------ ------ EMEA ------
    EU-West-AMS eu-west-ams.sip.flowroute.com
    EU-West-LDN eu-west-ldn.sip.flowroute.com
    ------ ------ LATAM ------
    SA-East-SP sa-east-sp.sip.flowroute.com
  2.  RTP media (call audio): To reduce latency, Flowroute uses Direct Media Delivery. To receive Direct Audio, allow UDP packets from any source IP address with a destination port within your system's RTP public media port range.[2]

[1] If your system has issues connecting over port 5060, you can use 5160 as an alternate SIP port. 

[2] RTP media port range varies by phone system. Your system's RTP media port range will be configured locally on your order and detailed in your system documentation.
