Example 1: SIP-to-SIP Calling/Answering
Applications:
The SIP-to-SIP calling works when both calling and answering parties are registered to SIP server
with given registered phone numbers. The ADSL connections can be as in either Diagrams A or B.
Both parties are registered to SIP server under NAT router. For Diagram A without NAT router, you
may select NAT mode to enable the embedded NAT router. For Diagram B with external NAT
router, you may select Bridge mode to disable the embedded NAT.
Configurations:
1. Select either “NAT“ or “Bridge” in accord with your network in “WAN settings” page,
2. Select “DHCP Client” to automatically get an IP address from NAT router.
3. Remember to click the “Submit” button,
4. Select Active “ON” in the “SIP settings / Service Domain” page,
5. Enter the Register Name, Register Password, Proxy Server, and Outbound Proxy,
6. Select “ON” in the “STUN setting”, if Outbound Proxy is NOT available.
7. Upon successful SIP registration, the REG LED indicator will be ON and the LCD will show
registered <phone number>.
