Step 7: Make phone calls.
Note: For your easy understanding and manipulation, all examples given in this step do not
involve registration, that is, SIP initiates calls in a point-to-point mode.
Situation 1: Call from a station to another (TelÆTel)
The gateway allows two FXS ports to call each other by default. Just use a station connected with
an FXS port to dial the number of the destination FXS port and you can make a TelÆTel call. The
default number of an FXS port is 80XX, among which XX represents the corresponding port
number. For example, the default number corresponding to Port 1 is 8001, and that corresponding
to Port 8 is 8008.
Actually a TelÆTel call on the gateway is accomplished via the routing of TelÆIPÆIPÆTe l . F o r
detailed introductions and configuration guide, refer to
Q2 in Appendix B.
Situation 2: Call from a station to an IP phone (TelÆIP)
1. Go to ‘Advanced Settings Æ Dialing Rule’ on the WEB interface and click the ‘Add New’
button to add a new dialing rule. Refer to
3.5.9 Dialing Rule for detailed instructions. Enter
either a particular number or a string of ‘x’s to represent several random numbers. For
example, ‘xxx’ denotes 3 random numbers. You may use the default value of ‘Index’ and are

2. Go to ‘Port Settings Æ Port Group’ on the WEB interface and click the ‘Add New’ button to
create a new port group and add FXS ports which are connected with stations to it. Refer to
3.6.3 Port Group for detailed instructions. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the FXS port which is connected with a station is Port1, check the
checkbox before Port1, set Index to 1, fill in Description with test, and keep the default
values of other configuration items.
3. Go to ‘Route Settings Æ TelÆIP’ on the WEB interface and click the ‘Add New’ button to add
a new routing rule. Refer to
3.7.3 TelÆIP for detailed instructions. Select the port group
created in Step2 as ‘Source Port Group’ and fill in ‘Destination IP’ and ‘Destination Port’ with
the IP address and the Port number you plan to call. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the remote IP address intended to call is 192.168.0.111 and the port is
5060. Set Index to 63, Source Port Group to 1, fill in Description with test, configure
Destination IP to 192.168.0.111, Destination Port to 5060, and keep the default values of
other configuration items.
4. Pick up the station and dial the number set in Step1 to ring the remote IP phone. If you have
set a particular number in Step 1, only this number you can dial; if you have set a string of ‘x’s,
how many ‘x’s there are, how many random numbers you can dial.
Example: Pick up the station and dial 123. Then the IP phone with the IP address
192.168.0.111 and the port 5060 will ring.
Situation 3: Call from an IP phone to a station (IP ÆTel)
1. Go to ‘Port Settings Æ Port Group’ on the WEB interface and click the ‘Add New’ button to
create a new port group and add FXS ports which are connected with stations to it. Refer to
3.6.3 Port Group for detailed instructions. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the FXS port which is connected with a station is Port1, check the
checkbox before Port1, set Index to 1, fill in Description with test, and keep the default
values of other configuration items.
2. Go to ‘Route Settings Æ IPÆTel’ on the WEB interface and click the ‘Add New’ button to add
a new routing rule. Refer to
3.7.2 IPÆTel for detailed instructions. Fill in ‘Source IP’ with the
IP address which initiates the call and select the port group created in Step1 as ‘Destination
Port Group’. You may use the default values of other configuration items and required not to
leave ‘Description’ empty.
Example: Provided the IP address of the IP phone which initiates the call is 192.168.0.111.
Set Index to 63, Destination Port Group to 1, fill in Description with test, configure Source
IP to 192.168.0.111, and keep the default values of other configuration items.
3. Pick up the IP phone and call the IP address and port of the SMG-B analog gateway to ring
the station.
Example: Provided the IP address of the SMG-B analog gateway is 192.168.0.101 and the
port is 5060, use the IP phone to call the IP address 192.168.0.101 and the station connected
with Port1 will ring.
Step 8: Enable the auto dial feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the auto dial feature and set the parameters ‘Auto Dial
Number’ and ‘Wait Time b efore Auto Dial’. If there is no dialing operation in a time period (i.e. Wait
Time before Auto Dial) after pickup, the port will automatically call the preset number (i.e. Auto
Dial Number). Refer to
3.6.1 FXS for detailed instructions.
Synway Information Engineering Co., Ltd
SMG-B Series Analog Gateway User Manual (Version 1.1.0) Page 12
Step 9: Enable the DND (do not disturb) feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the DND feature. Then, the FXS port will reject all
incoming calls. Refer to
3.6.1 FXS for detailed instructions.
Step 10: Enable the call waiting feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the call waiting feature. Then the corresponding FXS
port while in conversation can accept another call from IP and keep it in the waiting state. Once
the current conversation is finished and the station hangs up, the call in the waiting state will ring
the station and wait for answer . During the time in the waiting st ate, it will always hear the ringback
tone from the FXS port. Refer to
3.6.1 FXS for detailed instructions.
Step 11: Perform call forwarding. (Skip this step if not necessary.)
Situation 1: Hook-flash operation
Figure 2-3 Call Forward via Hook-flash
As shown above, Remote A initiates and establishes a call with Station. Then by a hook-flash
operation, that is, a rapid clap on the hook or pressing the ‘flash’ button on the phone set, Station
can forward the call to Remote B.
Once a flash is generated, Station will go into the dialing state ( the FXS port sends it dialing tones)
before it dials the forwarding number.
If the dialing succeeds, the FXS port will send ringback tones to S t ation. Provided Remote B picks
up the call, at this time Station can:
a) Directly talk with Remote B;
b) Perform another hook-flash operation to switch the call to either Remote A or Remote B.
c) Hang up to make Remote A and Remote B go into a direct talk with each other.
If the dialing fails, the FXS port will send busy tones to Station. At this time Station can:
a) Hang up to go back to the ringing state; then pick up the call again to recover the talk
with Remote A.
b) Perform the hook-flash operation again without hanging up the call to recover the talk
with Remote A.
Once Station recovers the call with Remote A, it can forward the call again by a new hook-flash

tone to let the subsequent call procedure go out of your control.
3.5.9 Dialing Rule
Considering efficiency, it is not acceptable that the gateway reports to the PBX or relevant devices
every time it receives a number. Instead, we hope that the gateway can automatically judge the
received number to see if it meets the set rule, if it is complete and if it is qualified to make
outgoing calls. Therefore, a whole dialing plan, which consists of multiple dialing rules specifying
the auto judging conditions, is required. Each dialing rule has a priority, which is used to restrict
the sequence and avoid conflict.

Appendix B Troubleshooting
Q1. What to do if I forget the IP address of the SMG-B gateway?
There are two ways to get the IP address:
1) Long press the Reset button on the gateway to restore to factory settings. The default IP
address is 192.168.1.101
2) Dial the corresponding function key through an FXS port to query the IP address. See
3.5.8 Function Key for more details.
Q2. The SMG-B gateway only supports routing on two directions, i.e. TelÆIP and IPÆTel.
What to do if I want to make a TelÆTel call?
By default, you can make TelÆTel calls without any routing configuration.
If you need to make TelÆTel calls in a specific way, try via the routing of TelÆIPÆIPÆTel.
See below for detailed introductions.
Provided you are going to initiate a call from Port Group 1 to Port Group 2; the IP address and
port number of your gateway are 192.168.1.101 and 5060 respectively.
a) Add a new routing rule on the TelÆIP routing rule configuration interface. Select a port
group (e.g. Port Group 1) as ‘Source Port Group’ to initiate the call and fill in ‘Destination
IP’ and ‘Destination Port’ with the gateway’s IP address (e.g. 192.168.1.101) and port
number (e.g. 5060). Then the call initiated from the station corresponding to Port Group
1 will be routed to the gateway.
b) Add a new routing rule on the IPÆTel routing rule configuration interface. Fill in ‘Source
IP’ with the gateway’s IP address (e.g. 192.168.1.101) and select a port group (e.g. Port
Group 2) as ‘Destination Port Group’ to be called. Then if the IP end of the gateway calls
itself, the station corresponding to Port Group 2 will ring.
c) Finishing the above configurations, you can perform a TelÆTel call from Port Group 1 to
Port Group 2 simply by the way you make a TelÆlP call.
Q3. Does call forwarding involve routing and number manipulation?
Case 1: If the forwarding number is the number of the gateway port. There is no need to use
routing and number manipulation rules. Because the gateway will find the corresponding
number according to the forwarding number and make a call.
Case 2: If the forwarding number is not the number of the gateway port. It is required to use
routing and number manipulation rules. A call forward procedure can be regarded as a
TelÆIP call. It uses the routing rules and number manipulation rules in the same way as the
TelÆIP call. A complete call forward is performed as follows:
a) An incoming IP call to the gateway rings the port which matches the IPÆTel routing and
number manipulation rules and obtains a new CallerID.
b) Then the gateway uses the newly obtained CallerID and the call forward number, via the
TelÆIP routing and number manipul ation rules, to make another call from the port to a
remote IP address.
Q4. In what cases can I conclude that the SMG-B gateway is abnormal and turn to
Synway’s technicians for help?
a) During runtime, the run indicator does not flash or the alarm indicator lights up or flashes,
Synway Information Engineering Co., Ltd
SMG-B Series Analog Gateway User Manual (Version 1.1.0) Page 95
and such error still exists even after you restart the device or restore it to factory settings.
b) Voice problems occur during call conversation, such as that one party or both parties
cannot hear the voice or the voice quality is unacceptable.
c) The port of the gateway is well connected, but the channel indicator never lights up after
the gateway startup or the color it lights up does not comply with the actual state or port
type.
Other problems such as inaccessible calls, failed registrations, incorrect numbers and
abnormal dialing operations on the FXS port are probably caused by configuration errors. We
suggest you refer to
Chapter 3 WEB Configuration for further examination. If you still cannot
figure out or solve your problems, please feel free to contact our technicians.
Q5. What to do if I cannot enter the WEB interface of the SMG-B gateway after login?
This problem may happen on some browsers. To settle it, follow the instructions here to
configure your browser. Enter ‘Tools > Internet Options >Security Tab’, and add the current IP
address of the gateway into ‘Trusted Sites’. If you changes the IP address of the gateway,
add your new IP address into the above settings too.
Q6. How many ports can be rung by turns according to the Ringing by Turns rule?
According to the 180s ringing timeout limit in RFC3261 protocol, the time used for ringing all
ports by turns cannot exceed 180s. Therefore, based on the minimum timeout 15s for each
port in the ringing queue, the maximum number of ports for ringing by turns is 12.
For example, if you set Timeout for Ringing by Turns to 20s, the maximum number of ports
for ringing by turns should be 180s/20s=9; if you set Timeout for Ringing by Turns to 30s,
the maximum number of ports for ringing by turns should be 180s/30s=6.
Q7. Is there any cell-phone APP can make calls to the SMG-B gateway?
Yes. Linphone is a soft SIP phone that is supported by multiple platforms, such as Linux,
Windows, iOS, Android, etc. It must be registered to the SIP registrar server before dialing to
other SIP devices or PSTN telephones,
Q8. Does the SMG-B gateway support fax?
Yes. Currently the SMG-B gateway supports two fax modes: T.38 and Pass-Through.
Q9. Which RTP codecs are supported by the SMG-B gateway?
At present, the supported RTP codecs are: G.711A, G.711u, G.729, G.723, G.722, AMR and
iLBC.
Q10. How to configure the features Communication without Power and Communication
without Network for the SMG analog gateway?
The feature Communication without Power is implemented with the help of composite
modules equipped in the gateway. Once the power to the device is cut off, the station which
is linked with the FXS port on the composite module and the trunk which is linked with the
FXO port on the same module will connect to each other directly and keep the good
communications between phones and networks. What you need to do is just to configure the
composite module properly at your purchase of our gateway.
The feature Communication without Network is implemented via the WEB management
over the analog gateway. It will automatically route a call to the FXO port in case of network
failure or call timeout.
