Our gateways use the following IP addresses and UDP ports for SIP and RTP/UDPTL packets. They will speak SIP to you on either port 5060 or 5080. Use of the non-standard port 5080 is recommended, and discussed in more detail here. The other ports mentioned are for RTP or UDPTL, the media streams. The SIP packets and RTP packets for a single session will often use different IP addresses.
