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 in the SMG Analog Gateway Manual.

The SMG gateway only supports routing on two directions, i.e. TelIP and IPTel. What to do if I want to make a TelTel call?

By default, you can make TelTel calls without any routing configuration. If you need to make TelTel calls in a specific way, try via the routing of TelIPIPTel. 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 TelIP 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 IPTel 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 TelTel call from Port Group 1 to Port Group 2 simply by the way you make a TellP call.

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 TelIP call. It uses the routing rules and number manipulation rules in the same way as the TelIP call. A complete call forward is performed as follows: a)An incoming IP call to the gateway rings the port which matches the IPTel 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 TelIP routing and number manipulation rules, to make another call from the port to a remote IP address.

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. 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 in the SMG Analog Gateway Manual. If you still cannot figure out or solve your problems, please feel free to contact our technicians.

What to do if I cannot enter the WEB interface of the SMG 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.

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. Refer to Q2 in this chapter for detailed information.

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.

Is there any cell-phone APP can make calls to the SMG 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,

Does the SMG gateway support fax?

Yes. Currently the SMG gateway supports two fax modes: T.38 and Pass-Through.

Which RTP codecs are supported by the SMG gateway?

At present, the supported RTP codecs are: G.711A, G.711u, G.729, G.723, G.722, AMR and iLBC.
