„ DialPlan: Define the dialing plan for Extension. It specifies the location of the
instruction used to control what the phone is allowed to do, and what to do with
incoming calls for this extension. In this field, you can Choose 5 dial level for Extension,
including [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
DialPlan can call to Extension and Route Level with R1. [ext+R12] means the
subscriber with such DialPlan can call to Extension and Route Level with R1 and R2.
[ext+R123] means the subscriber with such DialPlan can call to Extension and Route
Level with R1, R2 and R3. [ext+allroutes] means the subscriber with such DialPlan can
call to Extension and Route Level with R1, R2, R3 and R4.
Note:
•
For more information about Route Level, please refer to the user manual:

„ Keypad: User can select Keypad type to be RFC2833, In-band, SIP-Info and Auto.
You can choose Auto to auto select the Keypad type. Choose RFC2833, Inband or
SIP-Info here will force the Extension use RFC2833, Inband or SIP-Info only and the
setting should be also match the Keypad setting of Extension device.
Note:
• Now ePBX-100A-128 could not support G729 with Inband Keypad type. If
ePBX-100A-128 detect the caller or callee not support RFC2833 DTMF type.
Then ePBX-100A will force the Codec to G711 to make sure the DTMF detection
is correctly .
„ NAT Traversal: If the Extension device is behind a device performing NAT, such as
firewall or router, and need to register to ePBX-100A-128 on public network, then user
has to enable this function. Enable NAT Traversal to force ePBX-100A-128 to ignore
the contact information for the Extension and use the address from which the packets
are being received.
„ RTP Mode: User can choose for two type of RTP mode, one is Routed Mode another
is Direct Mode. The voice media will be routed “Peer-to-Peer” if two clients are both
setting to Direct Mode. This way will improve the voice quality and reduce the
performance wastage of the ePBX-100A-128.
Note:
•
If one peer set to Direct Mode but another peer set to Routed Mode, the result will
become to Routed Mode.
•
Voice media will still go through the ePBX-100A-128 if the ePBX-100A-128 needs
to detect DTMF.
•
If you enable the NAT Traversal function for Extension, the RTP mode will change
