2 Quick Installation
2.1 Installation Attentions
To avoid unexpected accident or device damage, please read the following
instructions before installing the device:
⚫The device is equipped with both RJ45 and RJ21 ports;
⚫Anti-jamming: to reduce the interference with telephone calls, it’s highly
recommended that telephone lines connected to the gateway should be
placed away from power cables;
⚫Power supply: the power adapter of the device accepts 100-240V AC power
supply. Please ensure safe and stable power supply (The DAG2500-48/72S
supports a dual 220v power supply or dual 48v power supply).
⚫Network bandwidth: please ensure there is enough network bandwidth so as
to guarantee stabilized running of the gateway;
⚫Ventilation: to avoid overheating, please do not pile up the gateway with
other devices and make sure the gateway has good ventilation around;
⚫Temperature and humidity: to avoid any accident that might cause
malfunction, it’s advised to install the gateway in an equipment room where
temperature and humidity are appropriate;
⚫Mechanical load: please make sure the gateway is placed steadily to avoid
damage. It is highly advised to horizontally place the gateway on a flat surface
or a cabinet.

⚫Connect gateway with network via a switch
⚫Connect FXS ports with analog phones, connect gateway with power input
and grounding lug

3 Basic Operation
12
3 Basic Operation
3.1 Methods to Number Dialing
There are two methods to dial telephone number or extension number:
⚫Dial the called number and wait for 4 seconds for dialing timeout, or dial the
called number directly (the system will judge whether the dialing is
completed according to Digitmap and Regular Expression dial plans).
⚫Dial the called number and press #.
3.2 Call Holding
If a calling party places a call to a called party which is otherwise engaged, and
the called party has the call holding feature enabled, the called party is able to
switch to the new incoming call while keeping the current call holding on by
dialing *# or pressing the flash button/flash hook.
When the called party dials *# once again or presses the flash button/ flash hook
once again, he or she will switch back to the first call.
3.3 Call Waiting
If a calling party places a call to a called party which is otherwise engaged, and
the called party has the call waiting feature enabled, the calling party will hear
a IVR voice ‘Please hold on, the subscriber you dialed is busy’ and the called
party will hear three beeps if waiting tone is enabled.
By pressing the flash button or the flash hook, the called party is able to switch
between the new incoming call and the current call.

3 Basic Operation
13
3.4 Call Transfer
3.4.1 Blind Transfer
Blind transfer is a call transfer in which the transferring party connects the call
to a third party without notifying the third party.
Example: A gives a call to B and B wants to blindly transfer the call to C.
Operation instructions are as follows:
1. A dials the extension number of B;
2. The extension of B rings, and B picks up the phone. Then A and B go into
conversation;
3. B presses the flash button (or flash hook), and dial *87* after hearing a dialing
tone to trigger blind transfer. Then B dials the extension number of C (end up
with #).
4. The extension of C rings, B hangs up the phone and C picks up the phone.
Then C and A goes into conversation.
Note:
⚫On the ‘Advanced →Feature Code’page, blind transfer should be enabled.
⚫If B hears continuous busy tones after he dials the extension number of C, it
means the call has timed out.
3.4.2 Attended Transfer
Attended transfer is a call transfer in which the transferring party connects the
call to a third party after he confirms that the third party agrees to answer the
call.
Example: A gives a call to B and B wants to attended transfer the call to C.
Operation instructions are as follows:
1. A dials the extension number of B;
2. The extension of B rings, and B picks up the phone. Then A and B go into
conversation;
