Appendix B Troubleshooting
1. What to do if I forget the IP address of the SMG gateway?
Long press the Reset button on the gateway to restore to factory settings. Thus the IP
address will be restored to its default value:
LAN1: 192.168.1.101
LAN2: 192.168.0.101
2. The SMG gateway only supports routing on two directions, i.e. Tel
Æ
IP and IP
Æ
Tel.
What to do if I want to make a Tel
Æ
Tel call?
You can make a Tel
Æ
Tel call via the routing of Tel
Æ
IP
Æ
IP
Æ
Tel. 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 Tel
Æ
IP routing rule configuration interface (See Figure
3-28). 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. LAN1:
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 IP
Æ
Tel routing rule configuration interface (See Figure
3-25). Fill in ‘Source IP’ with the gateway’s IP address (e.g. LAN1:
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 Tel
Æ
Tel call from Port Group 1 to
Port Group 2 simply by the way you make a Tel
Æ
lP call.
3. Does call forwarding involve routing and number manipulation?
Yes. A call forward procedure can be regarded as a Tel
Æ
IP call. It uses the routing rules and
number manipulation rules in the same way as the Tel
Æ
IP call. A complete call forward is
performed as follows:
a) An incoming IP call to the gateway rings the port which matches the IP
Æ
Tel 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
Tel
Æ
IP routing and number manipulation rules, to make another call from the port to a
remote IP address.
4. In what cases can I conclude that the SMG 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,
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.
