Your Domain & SIP Proxy will need to be set to sip.nehos.com.au (180.94.236.10) to use this network.
The sip.nehos.com.au domain supports SIP signaling on UDP/TCP on port 5060
You will need to allow your Customer Premises Equipment (CPE) to allow use of the 180.94.236.0/27 and 180.94.237.0/27 for SIP signaling and RTP media.
For CPE equipment that uses STUN the signaling will be TCP or UDP protocol on port 5060.
* We highly recomend using UDP protocol for SIP and RTP.
