2. In some special situations, phones under same local network could not set up connection
successfully when STUN is enabled. Because some NATs would refuse to transmit data packets on two
binding ports over NAT. So default setting of STUN is disabled. STUN could be enabled by web user
interface or importing configuration file.
Configuration method:
1. Web user interface
1) Click ‘Line/Basic Settings ’.
2) Modify the field ‘STUN Settings/ Server Address’ with domain name of STUN sever or IP address.
3) Click the “Apply” button to save the change.
4) Click ‘Line/SIP/Advanced Settings’ when Line 1 needs to use STUN to do NAT Traversal.
5) Make sure that ‘use STUN’ checkbox is checked.
6) Click the ‘Apply’ button to save the change.
