 Realm: Realm of ITSP or another EZLoop® IP-PBX Enterprise SIP Server.
Note:
•
When a call was sent form EZLoop® IP-PBX Enterprise SIP Server to a remote
SIP-Trunk, the SIP-Trunk may attempt to authenticate the “call”. So EZLoop® IP-
PBX Enterprise SIP Server should reply the correct Account ID and Password.
How does the EZLoop® IP-PBX Enterprise SIP Server know which ID and
Password it should send? When the call is going to SIP-Trunk via EZLoop® IP-
PBX Enterprise SIP Server, the SIP-Trunk may reply a 407 code, which will
contain a parameter called “Realm” for authentication, EZLoop® IP-PBX
Enterprise SIP Server will re-send the call again and contains correct ID and
Password based on the Realm. So the Realm should be unique. For more
information about Realm, please contact with your ITSP.
•
If you have multiple EZLoop® IP-PBX Enterprise SIP Server, you may hope
those EZLoop® IP-PBX Enterprise SIP Server could call to each other. You
should set the Extension to let those EZLoop® IP-PBX Enterprise SIP Server
can register to each other, and you should also confirm the [Realm] in the page
of Configuration IP PBX. For more information, please refer to the user
manual: CH5. Appendix-Application between CPE device and EZLoop® IP-
PBX Enterprise SIP Server.
 Status: Once SIP Trunk is configured and enabled, here will show the registration
status.
Press Apply to save configuration, or press Cancel to quit configuration.

Server. Enter Configuration  Routing Table-select direction and press Add New to
