nexMatrix Host Names and IP addresses

nexMatrix SIP trunk service will connect to your IP PBX from one or more of these servers. You may need to whitelist these addresses and/or host names to allow unsolicited inbound traffic from them to your PBX on UDP port 5060 and whatever range of RTP ports your PBX is configured for .  For outbound traffic from your PBX, our servers are expecting SIP signaling packets on port 5060 UDP and RTP media streams in the range of 10000 to 20000 UDP.
