Realm
Realm configuration of ITSP SIP Server or another ePBX40 or
IP-PBX.
Note:
When a call was initiated from ePBX40 to a remote SIP
Trunk, the remote SIP Server or IP-PBX may attempt to
authenticate this Call for security consideration. ePBX40
should reply correct Account ID and Password to remote
Server or IP-PBX. How does ePBX40 know which ID and
Password it should send? When the call is going to SIP
Trunk via ePBX40, the remote SIP Server or IP-PBX may
reply a 407 code (SIP protocol format) to ePBX40, which
contains a parameter called “Realm” for authentication.
ePBX40 will re-sent this call and contains correct ID and
Password based on the Realm which was configured here.
The Realm should be unique
. For more information
about Realm, please contact with your ITSP Service
provider’s or remote SIP Server technician.
If you have multiple ePBX40s to connect in a group, you
may want those ePBX40s to call each other. You should set
up the Extension to let those ePBX40 can register to each
other (other IP-PBX), and you should configure unique
[Realm] in the webpage of
Configuration
IP PBX
.
