The Obi100 is a 1-phone port ATA adapter that support SIP VoIP services, the OBi100 is perfect for customers who do not have a traditional phone service, yet need similar solution and want the savings and simplicity of using a VoIP service for all their calls. To start configuring your Obi100 you will need to plug it to your router/modem via its Internet port with an Ethernet cable and connect a regular handset phone to its Phone port, then follow the next steps.


Manual Configuration details

**NOTE : You may use this guide to configure an Obi110 as well.

Dial * * * then press 1 to confirm from the connected phone, to get the IP address of your device. This will be a number similar to Once you get the IP address, enter it in the URL address bar "http://" of your Internet Browser to get access to the Graphic User Interface of the Obi100. If done properly, the following window should appear on your screen:


Once you get the Authentication Required window you will be prompted for a User Name and Password, the default credentials are:

User Name: admin

Password: admin

After this, you should now be able to see the Obi Web interface. Now on the left side of the screen please find the next options and follow the next steps:

Service Providers >> ITSP Profile A >> SIP

In this section you can set the server and the port that you wish to register to.


    Please note that in order to change the settings, you need to Uncheck the Default box on the right hand side. 
  • ProxyServer: (one of our multiple servers, you can choose the one closer to your location.)
  • ProxyServerPort: 5060
  • RegistrarServer: (one of our multiple servers, you can choose the one closer to your location.)
  • RegistrarServerPort: 5060

Service Providers >> ITSP Profile A >> General

In this section you can set the Name, protocol and DTMF method to connect through.


  • Name: 100000 (Replace with your 6 digits Main SIP account UserID or Sub Account user name, i.e. 123456 or 123456_sub)

Voice Services >> SP1 Service

In this section you can set your Main account/sub_account credentials like User name and Password. The Main account password by default is the same password as the Customer portal.


  • AuthUserName: 100000 (Replace with your 6 digits Main SIP account UserID or Sub Account user name, i.e. 123456 or 123456_sub)
  • AuthPassword: ********* (SIP Account Password)

Checking your Voicemail

If you encounter any issues when you try to check your VoiP.MS Voicemail. Please try the following suggestions.

Try changing your Dial plan. Replace the 555 digits in the following lines by the area code of your choice and copy the line, including parenthesis, in the Digitmap field in the ITSP Profile:

Default Dial Plan:


Dial Plan to allow you to dial other numbers plus those beginning with * followed by one or more numbers:


Dial Plan to allow you to dial other number plus *97 and *98 ONLY:


Also, some clients have been successful by dialing **1 and *97 for line 1 or **2 and *97 for line 2.

An additional note regarding Outbound Calling

In at least one instance it was necessary to specify a non-default outbound calling route in the Obi110 to be able to place calls using the service. The default setting had the Obi110 attempting to place calls using the PSTN port on the device. The relevant setting is:

Physical Interfaces >> PHONE Port

  • PrimaryLine: (Select from drop-down)


The default is PSTN. Select SP1 Service if you only have one SIP account configured on the device. Select Trunk Group 1 to have it attempt to place calls using SP1 first, then SP2. Additional Trunk groups can be configured under Voice Services >> Gateways and Trunk Groups.

Configuration Using OBi Dashboard

I had added my device to the OBitalk network prior to trying the manual configuration details given on this page. I then attempted the manual configuration explained above. I found that after I submitted the changes, the settings would revert back to the default values after a short amount of time (I suspect a configuration mismatch was detected by the OBiTalk network and the previous configuration was automatically restored, but this is just supposition on my part). By configuring the device through the OBitalk dashboard and selecting as the service provider the device was up and working with little effort.

Add your device to the OBitalk service in the OBi Dashboard [1]. Instructions for this are included with the obi110 and are not discussed here.

After the obi110 is added, edit the device. You can select Service Provider 1 or Service Provider 2 under the Configure Voice Services heading. This will take you to a page where you can select Follow the instructions and once you are done the configuration will be downloaded to your obi110.

10 Second Delay Reaching Voicemail Attendant when dialing *97 or *98

The Obi 100, 110 and 202 devices have non-configurable 'short' and 'long' delays if a dialed sequence does not match a digitmap. So you may have a 10 second delay when you dial into your voicemail because of the built-in 'long' delay. This can be resolved in a couple of ways. Simply dial a # sign after you dial *97 or *98. Or include literals in your digitmap under the Service Provider / ITSP profile A or B / General / digitmap. Here is an example digitmap with a *97 literal included:


The literal in the example is '*97'. You could also add a literal for '*98'.

Then when you dial *97, the device immediately sends it instead of waiting 10 seconds.

Read more on digitmaps under the topic Digit Map Configuration in the Obi Device Admin Guide.

Known Issues and Resolutions

If you experience random call drops while in the middle of a call or if the person you talk to remains silent for over a minute (60 seconds by default), OBi will hang up the call. Please go here and check and increase this setting (Physical interface -> LINE port -> DetectFarEndLongSilence / SilenceTimeThreshold)

If you start to receive phone calls in the middle of the night, this is due to SIP scanners and is no fault of

To resolve this just disable by unchecking Enable for SP2 and OBiTALK under your Voice Tab.
You can also change your Obi Firewall Setting X_InboundCallRoute to : {(?|x|xx|xxx|xxxx|xxxxx|xxxxxx|[email protected]@.|[email protected]@.):}, ph
This will only allow 7 digit or greater numbers through.

If you plan on using the Phone Book in your Customer Portal and Speed Dial *75.

Please log into your OBI and change the built-in speed dial code from *75 in the device to something else.
