20.1 Configuring SIP Interfaces
The codec supports dialing over two SIP interfaces simultaneously.
Important Notes:
1. SIP interfaces are disabled by default.
2.
SIP1 is configured to use LAN1 by default, which is mapped to the Primary Via
interface by default.
3. SIP2 is configured to use LAN2 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. LAN1 or
LAN2 .
5. SIP1 and SIP2 can however 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 Address text box 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. Note: Do not enter a
Public IP Address if STUN is
configured. They cannot be used together because both will attempt to use a public IP
address over SIP. STUN settings are prioritized and used if both are configured.
To configure SIP1 or SIP2 :
1. Press the SETTINGS button, then navigate to SIP and press the button.
2. Navigate to SIP Interfaces and press the button.
3. Select either SIP1 or SIP2 and press to view and edit settings. Note: A SIP interface
must be disabled before settings can be edited.
