This FAQ describes, how you can configure 2N® VoiceBlue 2N® VoiceBlue Next gateway (You can also use 2N® 2N® VoiceBlue Max, 2N® 2N® BRI Lite and /Enterprise or 2N® 2N® StarGate and 2N® 2N® BlueTower as the configuration is basically the same) together with 2N® 2N IP intercoms and 2N® 2N® Access Unit for the school scenario. You can configure the intercom to send SMS message through the gateway as a conformation confirmation that a student has arrived to school. Once student will swipe the card to open the door, SMS to parent cell phone will be senda parent cellphone is sent. Below you can find a step by step configuration for both devices. FW version of 2N® 2N IP Intercom has to be 2v2.16 at least or higher and for 2N® 2N® VoiceBlue Next has to be at least 1v1.26.3. Please keep on in mind that even when you will have multiple entrances with the intercoms, you still need just only one gateway!

How to configure 2N® VoiceBlue 2N® VoiceBlue Next 

Note: As the very first step please make sure that the license for Email2SMS feature is uploaded into your 2N®VoiceBlueNext2N® VoiceBlue Next gateway. This license is sold as a package for 10 users (you can buy licence for 10, 20, 30, etc. users) and you can have up to 200 licensed users in the gateway. If you want to verify whether you have the correct license uploaded in your gateway, go to section "Management -> License key". You should see the licenses called SMSE and SMSUx and in the "Active" row. SMSE indicates that Email2SMS function is enabled and SMSUx indicates number of licensed users where x stands for this number  (see the picture below). If there is 's not a license for Email2SMS (SMSE) then you will not see tab won't see the "Messaging" on the top bar! menu. For each intercom you need one Email2SMS licence in the gateway!


As a next step you need to skip to the section "Messaging –> Users", click on the "Add" button and create new SMS user(s) who will send and receive SMS messages. There are several parameters in this section which have to be set. You need to select the communication protocol for SMS processing (SMTP/POP3 ) and assign the user to User group. Also do not forget to define the Login name (without domain) and Password to log into the SMS server via your e–mail client. You can see all parameters from this section in the picture below where was created user "Helios IP" with the login "SMS" and password "Helios". Once you fill in all parameters, click on the "OK" button. The user will be added and after that you have to make one more click to the "Save settings" button in the bottom right corner of the page (blue circle label in the picture).


In the picture below there is shown settings for User Group 1. Messages (emails) from all users in this User group are routed via SMS group 1. It means that these emails will be transferred to SMS and sent only via GSM modules assigned to SMS group 1. It is GSM module 2 in our example (as you can see in the picture from step 1).
