extensions) and your desire extensions(such as operator) or
Mobile phone (select one free FXO line to dial out or use SIP
trunk to dial) or City phone call.
Caller ID Detection
Your local Telco PSTN’s caller ID specification could be either
DTMF or FSK Bellcore protocol. You need to consult your local
PSTN company’s specification and give proper Caller ID type
configuration in order to detect and carry Caller ID to extension
when there is an incoming call.
Current Drop For

and what to do with incoming calls for this extension. In this

[ext-only], [ext+R1], [ext+R12], [ext+R123], [ext+allroutes].
You can define an “Outgoing call” record, to a certain Route
Level, as R1, R2…, etc. [ext-only] means this subscriber can
only call to Extension. [ext+R1] means the subscriber with
such Dial Plan can call to Extension and Route Level with R1.
[ext+R12] means the subscriber with such Dial Plan can call to
Extension and Route Level with R1 and R2. [ext+R123] means
the subscriber with such Dial Plan can call to Extension and
Route Level with R1, R2 and R3. [ext+allroutes] means the

NAT Traversal
If the Extension device is installed behind a device performing
NAT such as firewall or router, and need to register to ePBX40
on public network, this extension has to enable this function.
Enable NAT Traversal to force ePBX40 to ignore the contact
information for the Extension and use the address from which
the packets have 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,
ePBX40 will check “Fixed Outgoing Call Rule” first. If “Fixed
Outgoing Call Rule” is enabled, ePBX40 will confirm the Fix
Trunk ID for the calling party. That means the outbound call will

words, the receiver sees the forwarder’s extension number
instead.
