SIP Server Addresses

To allow Neural's VoIP traffic to flow through your firewall, please add an accept inbound & outbound rule for the following addresses: ( -


The ports required are:

  • 5060 UDP/TPC for signalling
  • 10000 - 20000 UDP for RTP audio


It is important that you do not forward these ports, but rather 'white list' or allow them through any ACL's on your router/firewall.


If you are using a custom built hosted solution or a call centre PBX, you will also need to add the IP for that server.
