the setting should be also matched the Keypad setting of
Extension device.
Note:
Now SIPPBX 6200A could not support G729 with Inband
Keypad type. If SIPPBX 6200A detect the calling party or
receiving party do not support RFC2833 DTMF type, SIPPBX
6200A will switch the voice Codec to G.711 to make sure the
DTMF detection is correctly
.
NAT Traversal If the Extension device is installed behind a device performing
NAT such as firewall or router, and need to register to SIPPBX
6200A on public network, this extension has to enable this
function. Enable NAT Traversal to force SIPPBX 6200A to ignore
the contact information for the Extension and use the address
from which the packets are been received.
Fixed Trunk ID User can define a Fixed Trunk for a certain extensions. When
such extension makes an outgoing call via routing table,
SIPPBX 6200A will check “Fixed Outgoing Call Rule” first. If
“Fixed Outgoing Call Rule” is enabled, SIPPBX 6200A will
confirm the Fix Trunk ID for the calling party. That means the
outbound call will be routed by Fixed Trunk ID, if you define the
Fixed Trunk ID for the calling party and you also enable “Fixed
Outgoing Call Rule”.
Note:
For more information about Fixed Outgoing Call Rule, please
refer to the user manual: CH3.1.8 Outgoing Routing.
Absolute Timeout Specific the timeout value for the outgoing calls. Please also go
to Outgoing Call Rule page to enable the Route Timeout
function to restrict talking time ( Toll Restriction ).
BLF Enable Busy Line Field function for extensions.
Forward CallerID By default, the “from header of SIP invite” will contain the
caller’s line number when forward function is activated. But this
may make some errors occurred for some SIP Trunk services.
So we add this function in the “Extension Setting” page, to let
user modify the line number of SIP Invite’ s from header, from
calling party’s number to the called party’s number.
Unconditional FWD Enable Unconditional forward function by adding forwarding
number.
No Answer FWD Enable No Answer forward function by adding forwarding
number.
