General SIP information¶
DIDWW originates calls to customers from the following endpoints:
22.214.171.124 - New York PoP
126.96.36.199 - Frankfurt PoP
188.8.131.52 - Los Angeles PoP
184.108.40.206 - Miami PoP
220.127.116.11 - Singapore PoP
These IP addresses correspond to our routing cluster exit nodes. For UDP transport we send signaling from port 5060. For TCP we use port range from 5070 to 5200
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.
