Two specific policies must be put in place on your network's firewall to ensure you receive all audio on Flowroute calls:
-
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 34.210.91.112/28 US-East-VA us-east-va.sip.flowroute.com 34.226.36.32/28 ------ ------ ASIA PACIFIC ------ AP-East-HK ap-east-hk.sip.flowroute.com 16.163.86.112/30
AP-Southeast-SIN ap-southeast-sin.sip.flowroute.com 3.0.5.12/30 ------ ------ EMEA ------ EU-West-LDN eu-west-ldn.sip.flowroute.com 3.8.37.20/30 EU-Central-FRA eu-central-fra.sip.flowroute.com 3.71.103.56/30 ------ ------ LATAM ------ SA-East-SP sa-east-sp.sip.flowroute.com 18.228.70.48/30 -
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]
NOTE: [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. |
