NAT Traversal If the Extension was installed behind firewall or router, and
need to register to ePBX80 which stay on physical internet
network, this feature has to enable. Enable NAT Traversal to
force ePBX80 to ignore the contact information to that
Extension and use the address from which the packets have
been received.
Fixed Trunk ID User can define a Fixed Trunk to one extension. When such
extension makes an outgoing call via routing table, ePBX80 will
check “Fixed Outgoing Call Rule” first. If “Fixed Outgoing
Call Rule” is enabled, ePBX80 will use the Fixed Trunk ID
for the calling party. That means the outbound call will be
routed by Fixed Trunk ID, if you define both Fixed Trunk ID and
enable “Fixed Outgoing Call Rule” for the calling party.
Note:
For more information about Fixed Outgoing Call Rule, please
refer to Chapter 3.2.7 Outgoing Routing.
Absolute Timeout Specify the timeout value for the outgoing calls. ePBX80 will
drop this call if receiver device do not response this call within
Timeout period. Please also go to Outgoing Routing page to
enable the Route Timeout function. See Chapter 3.2.7
Outgoing Routing in details.
BLF Enable BLF (Busy Line Field) function for this extension. In
general case, BLF was used with IP Phone with LCD display to
indicate your desire’s extension or FXO line busy status.
Forward CallerID By default, the “from header of SIP invite” contains the
Caller’s line number (Calling No.) when Forward function is
activated. But this may make error for some SIP Trunk
services. This feature provides an alternative feature to modify
line number of SIP Invite’s from header, from
Calling Party’s
number to Called Party’s number by selecting Ext No.
Unconditional FWD Enable Unconditional forward call to the number here. These
