2 Quick Installation
2.1 Installation Attentions
To avoid unexpected accident or device damage, please read the following instructions before you install the XonTel
Plus PBX.
The adapter of the PBX accepts DC input voltage of 12V 2A. Please ensure stable and safe power supply;
To reduce the interference to telephone calls, please separate power cables from telephone lines;
To guarantee stable running of the PBX, please make sure that there is enough network bandwidth;
For better heat dissipation, please place the PBX on a flat surface and do not pile up with other devices;
2.2 Installation Steps
Connect the power adapter to the power jack;
Connect PSTN lines to the FXO ports;
Connect network cable to the LAN port(s) and WAN port (please refer to 2.3 Network Connection);
2.3 Network Connection
XonTel Plus works in two network modes: route mode and bridge mode. When it is under the route mode, the IP
address of WAN port must be different from the IP address of LAN port. But when it is under the bridge mode, the IP
address of .WAN port and that of LAN port are the same.
Plus PBX

2.3.1 Network Connection Diagram under Route Mode
Under the route mode, the default IP address of .WAN port is a DHCP IP address, while the default IP address of the
LAN port is a static IP address, namely 192.168.11.1.
Note: The IP address of LAN port of the PBX and the IP address of PC must be at the same network segment, while
that of WAN port is at a different network segment.
2.3.2 Network Connection Diagram under Bridge Mode
Under the Bridge mode, the IP address of WAN port is the same with that of LAN port. Generally, when the PBX
works under the bridge mode, the IP address of the PBX has been modified. In the following diagram, it is assumed
that the IP address has been modified into 172.16.80.1.
Note: The IP address of PC and that of WAN port of the XonTel Plus PBX are at the same network segment.

2.4 Connect PBX to Network
2.4.1 Connect PBX to Network via Network Port
Please connect the XonTel Plus PBX to network according to the network diagrams in Section 2.3 Network
Connection. Connect a PSTN line to the FXO port. Use a mobile phone to dial the number of the FXO port, and then
dial *158# to query the IP address of LAN port after hearing IVR. Modify the IP address of PC to make it at the same
network segment of LAN port of the PBX.
You are also allowed to log in the PBX by using the WAN port, but you need to enable the port first.
2.4.2 Preparations for Login
Modify the IP address of the PC to make it at the same network segment with the XonTel Plus PBX, since the default
IP address of LAN port of the PBX is 192.168.11.1.
Check the connectivity between the PC and the XonTel Plus. Click Start Run of PC and enter cmd to execute
‘ping 192.168.11.1’to check whether the IP address of LAN port runs normally.
2.4.3 Login to Web Interface
Open a web browser and enter the IP address of LAN port (the default IP is 192.168.11.1). Then the login GUI will
be displayed.
You also can enter the IP address of WAN port, but it’s required to modify the IP address of PC to make it at the same
network segment with WAN port.
It is suggested that you should modify the username and password for security consideration.
By default, the username is admin, while the password is Xontel. After entering username and password, click Login
to enter into the web interface.
Under some circumstances, login of the Web will be limited：
For three consecutive login failures, you need to slide to validate your user account;
Failing to log in the Web for ten times consecutively, the IP address of the XonTel Plus device will be put into
the blacklist, and you need to reset a new IP address for the device；
Successful login or device restart will wipe out login failure records.

3 Basic Operation
3.1 Methods to Number Dialing
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 pressing the flash button or the flash hook.
When the called party presses the flash button or the 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.
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.
3.4 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 *3 to trigger blind transfer (at the same time,A can hear the waiting tone). Then B dials the extension
number of C (end up with # or wait for 4 seconds);
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 ‘Call Control Feature Code’page, feature code service should be ‘On’.
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;
3. B presses *2 to trigger attended transfer (at the same time, A can hear a waiting tone). Then B dials the extension
number of C;
4. Then one of the following situations will happen:
a. If the extension of C cannot be reached because the dialing/call has timed out, C rejects the call or C is
busy, B will automatically switch to the conversation with A.
b. The extension of C rings (at the same time, B can hear a ringback tone). If B hangs up the phone at this
moment, A will continue to hear the waiting tone. Then if A also hangs up the phone, the extension of C
will continue to ring. If C picks up the phone at this moment, the call will end directly.
c. The extension of C rings and then C picks up the phone. C and B go into conversation, and A will
continue to hear a waiting tone. If it’s B that hangs up the phone at this moment, C and A go into
conversation. If it’s C that hangs up the phone, B and A go into conversation.
3.5 Three-way Conference
When the SIP extension of XonTel Plus is the caller:
Step1. A dials the number of B and B picks up the phone, and thenA and B go into conversation;
Step2. A presses the flash hook, and then dial the number of C after hearing the dialing tone.
Step3. C pick up the phone, and A and C go into conversation and meanwhile the call between A and B is kept
holding.
Step4. Then, if A presses the flash hook and dials 1, the conversation will switch back to A and B; if A presses the
flash hook and dial 2 , the conversation will switch to A and C; if A presses the flash hook and dial 3, the conversation
will switch toA , B and C (three-party conversation).
When the SIP extension of XonTel Plus is the callee:
Step1. B places a call to A, and A picks up the phone after the phone rings. And then C also gives a call to A (at the
same time, A can hear a waiting tone).
Step2. If A presses the flash hook, A and C go into conversation and meanwhile the call between A and B is kept
holding.
After that, if A dials 1, the conversation will switch back to A and B; if A dial 2 , the conversation will switch to A and
C; ifA dials 3, the conversation will switch toA , B and C (three-party conversation).
Step2 (optional). When C is calling Aand B hands up the phone during the process, Aand C will automatically go into
conversation.

3.6 Switching Between Two Calls
When the SIP extension of XonTel Plus is the caller:
Step1. A dials the number of B and B picks up the phone, and thenA and B go into conversation;
Step2. A presses the flash hook, and then dial the number of C after hearing the dialing tone.
Step3. C pick up the phone, and A and C go into conversation and meanwhile the call between A and B is kept
holding.
Step4. If A presses the flash hook again, and the call will be switched back to A and B. If A presses the flash hook once
more, the call will be switched to A and C.
When the SIP extension of XonTel Plus is the callee:
Step1. B places a call to A, and A picks up the phone after the phone rings. And then C also gives a call to A (at the
same time, A can hear a waiting tone).
Step2. If A presses the flash hook, A and C go into conversation and meanwhile the call between A and B is kept
holding.
After that, if A presses the flash hook again, and the call will be switched back to A and B. If A presses the flash hook
once more, the call will be switched toA and C.
3.7 Send or Receive Fax
3.7.1 Fax Mode Supported
T.38（IP-based）
T.30（Pass-Through）

3.7.2 Explanation of T.38 and Pass-through
T.38 is an ITU recommendation for allowing transmission of fax over IP networks in real time. Under the T.38 mode,
analog fax signal is converted into digital signal and fax signal tone is restored according to the signal of peer device.
Under the T.38 mode, fax traffic is carried in T.38 packages.
Pass-through: Under the pass-through mode, fax signal is not converted and fax traffic is carried in RTP packets. It
uses the G.711A or G711U codec in order to reduce the damage to fax signal.
3.8 Function of RST Button
Press the RST button for different time length, and the XonTel Plus device will execute different function:
1. On the condition that the device is running normally, press the RST button for 3 to 6 seconds, the login password
of the device will be restored to the factory default, and the network mode will become the route mode, with WAN
address obtained through DHCP and LAN IP address defaulted as 192.16.11.1. At the meanwhile, the access ports of
Http, Https, Telnet and SSH are restored to the default settings.

2. On the condition that the device is running normally, press the RST button for 6 to 12 seconds, and all
configurations are restored to the default settings.
3. On the condition that the device is powered off, press the RST button and the WPS button, and connect the XonTel
Plus PBX with power source. After about 30 seconds, the device will wipe out all configurations, rebuild a file system
and then re-load a firmware version (this method is used in case of version fault).

3.9 Query IP Address and Restore Default Setting
Connect a PSTN line to the FXO port. Use a mobile phone to dial the number of the FXO port, and you can dial *158
to query the IP address of LAN port and dial *159 to query the IP address of WAN port.
If you want to restore XonTel Plus to default settings, you can press the RST button for 6 to 12 seconds or you can
configure it on the Web interface.
On the Web interface, click System Backup/Restore/Upgrade and then select the parts (system, network or
service) that need to be restored to default settings. Click Reset and then restart the device, and the selected parts will
be restored to default settings.
