Note: Before following this article, make sure that the SPA-962 is registered on SPA-9000.

Step 1:
You need to access the SPA's Web User Interface. Check your SPA-962 IP Address by dialing the menu button followed by 9. The IP address will be displayed on the LCD screen.

Step 2:
Launch your browser and type in http://IP_Address_of_your_SPA962 on the address field then hit Enter.

Note: You're now ready to check the SPA-962 settings. If the web interface is asking for a username and password, this means that the unit was locked by your Provider. Please contact your respective VoIP Provider for assistance.

Step 3:
From the SPA IP Phone configuration utility, click the Ext 1 tab. The voicemail setting should be entered in the Mailbox ID field in the following format:

<line#><User ID>

Where <line#> refers to the SPA9000 Line (1-4) of the SPA400 configuration and <User ID> must match the setting entered in the SPA400 Voicemail Users menu.

Step 4:  
After observing that the voicemail settings are in a correct format, you may want to try rebooting the IP phone. You can reboot your IP phone by pressing the menu button then dial 12.
