These IP addresses correspond to our routing cluster exit nodes. For UDP transport we send signaling from port 5060. For TCP and TLS we originating connections from port range 5070-65535
Our system sends RTP packets from the following subnets:
with RTP port-range: 1024-65535
We transmit and receive RTCP packets from port = rtp_port + 1 (as recommended in RFC3550). Additionally, we are able to receive RTCP packets on the same port as RTP, considering utilizing RTCP conflicts avoidance payloads (payload types 72-76).
The SRTP media encryption and TLS SIP transport are disabled by default. Please contact our sales team email@example.com to allow traffic encryption for your account.
