The codec supports dialing over two SIP interfaces simultaneously.
|
Important Notes: 1.SIP interfaces are disabled by default. 2.SIP1 is configured to use LAN by default, which is mapped to the Primary Via interface by default. 3.SIP2 is configured to use VLAN1 by default, which is mapped to the Secondary Via interface by default. 4.SIP1 and SIP2 each need to use a separate IP interface when connecting, e.g. LAN or VLAN1. 5.SIP1 and SIP2 can each make multiple SIP calls, e.g. two calls can be made over SIP1, or two calls can be made over SIP2. 6.The settings for SIP1 and SIP2 cannot be edited if the interface is enabled. 7.Enter a public IP address in the Public IP menu if you want to dial over SIP from behind a firewall. Then configure port forwarding to route traffic to the codec's local IP address behind your firewall. |

1.Press the the SETTINGS
