ArtDio IPS-2101h Passing Through the NAT/Firewall, SIP with Stun, SIP with Outbound Proxy

IPS-2101h User Manual

7. Passing Through the NAT/Firewall

When IPS-2101h works with NAT/Firewall, some of the following cases might happen:

1.With a valid account, IPS-2101h can not successfully register to the server.

2.IPS-2101h itself can make calls but is not able to receive calls.

3.One-way talk. One end can not hear any sound.

It might be the NAT/Firewall issues in these cases. IPS-2101h supports two methods to allow SIP passing through the NAT/Firewall by deploying STUN or Outbound Proxy.

7.1SIP with STUN

zService address：Enter the IP address or domain name of the SIP Proxy server.

zNAT traversal：Select “STUN” from the drop down list.

zNAT addr：Enter the IP address or domain name of the STUN server.

7.2SIP with Outbound Proxy

zService Address: Enter the IP address or domain name of the Outbound Proxy server. If the port of the Outbound Proxy is not 5060, please add “:” and the port number right after the Proxy server IP address.

zService ID：Enter the IP address or domain name of the SIP Proxy server.

zNAT traversal：Select “Disable”.
