Real-Time Protocol (RTP)

RTP is the protocol used to deliver audio and video over IP networks. RTP uses the UDP protocol because its efficient in low-quality networks such as phones communicating over the public internet. (NB – while your router sets the specific RTP port, we will accept communication between the 30-40k range).

TLS Support

We support TLS connections from devices that support this protocol for deployments that require increased security. You can use tls.2talk.com as your proxy/host but remember to set the transport to TCP via 5061.
