Appendix B Troubleshooting

Q1. What to do if I forget the IP address of the SMG 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 as follows:

LAN1: 192.168.1.101

LAN2 (disabled by default): 192.168.0.101

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 gateway only supports routing on two directions, i.e. Tel

IP and IP

Tel.

What to do if I want to make a Tel

Tel call?

By default, you can make Tel

Tel calls without any routing configuration.

If you need to make Tel

Tel calls in a specific way, try via the routing of Tel

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

IP 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. 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

Tel routing rule configuration interface. 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

Tel call from Port Group 1 to

Port Group 2 simply by the way you make a Tel

lP 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
Tel

IP call. It uses the routing rules and number manipulation rules in the same way as the

Tel

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

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

IP routing and number manipulation rules, to make another call from the port to a

remote IP address.

Q4. In what cases can I conclude that the SMG gateway is abnormal and turn to Synway’s
