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 from the following server IP addresses:
NOTE: If your system has issues connecting over port 5060, you can use 5160 as an alternate SIP port.

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.
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.
