Take TD-VG3631 as an example.

Some customers may face the problem that how my TD-VG3631 works with Asterisk server. Asterisk is a common VoIP server. In fact, TD-VG3631 can work with most VoIP servers. Different VoIP service providers use different servers, but the basic configuration is the same. Also the name of parameters that ISPs offer may be different in what display on TD-VG3631.

Here I take a Canada VoIP ISP: Scom as an example. Scom will offer you following parameters:



Port: 5060

Codecs: all

Phone number: *** (For example: 111)

Username: *** (For example: 111)

Password: *** (For example: 111)


NOTICE: Before configuring, you must confirm your device has access to the Internet!


Step 1: Open the web browser and type the LAN IP address of TD-VG3631 in the address bar, the default IP address of TD-VG3631 is, and then press Enter.


Step 2: Type the username and password in the login page, the default username and password both are admin.


Step 3: In Voice--> SIP Account, click ‘Add’ button.


Step 4: The options marked with “*” are necessary items, you must fill them in. As for other options, type them if your ISP’s offered those parameters. Or you should keep it by default.

You may find some parameters which the VSPs offered are different from what’s displayed on TD-VG3631. Here is how Scom’s parameters are related in TD-VG3631.


Username --> Authentication ID

Server --> Register Address

Proxy --> SIP Proxy


If you meet a similar situation, contact your VSP to confirm what the parameters they offered mean, and then type them in properly.


Step 5: After configuration above, click “Save”. After a while, if the “Status” shows “UP”, it means your SIP account has registered successfully.
