In this article we will explain how to set up a DECT system without any theoretical background. In this step-by-step tutorial we will use only one IP DECT master and one radio. Since both modules can be operated on the same IP1202/IP1203, you only need one base station. If you need more than one base station for your customer setup, you will see how easy it is to add as many base stations as you want.
DECT is used to transmit voice over the air. This means you can move freely around the house or office while talking on the phone without the need of a cable. In this guide we will explain all steps necessary to link your IP1202/IP1203, which are models of our DECT base station, to your PBX. This article does not go into full detail. If you want to know more, you are welcome to do our Advanced trainig.
- cordless communication
- This guide only explains how to set up DECT on one location.
- This article does not cover roaming.
- If calls get dropped due to a lack of coverage, you need to buy extra base station to increase the coverage area.
- innovaphone PBX
- IP1202 or IP1203 (All steps in this guide are the same for both models)
- 1 x SARI (50-00060-019)
- 1 x DECT handset like an IP64 or IP65
Things to know before you begin
- You need to know the PBX Password, which was created by the Install during the initial configuration of your PBX.
Create a DECT System object
The first step is to create a DECT System object in the PBX. This is done on the Advanced UI -> PBX/Objects. Select a DECT system object in the drop down menu and click on new.
Give this object a Long name. Please note that this name will be displayed on all DECT handsets. As a result, please select the name carefully.
Each user must have a hardware ID that corresponds to his name.
On the DECT tab of the user object, you must configure the following options:
- You must set the Gateway option (screenshot below) to the same name as the name of the DECT system object you created in the previous step.
- If you already know the IPEI of the DECT handset, you can enter it here. This is not mandatory, but you can skip a step later if you already enter the IPEI here.
- Please define a user AC. This user AC will be used later for the authentication of the DECT handset at the DECT system.
As the next step we will set up the LDAP replication between PBX and IP-DECT Master so that all necessary objects can be replicated to the IP-DECT Master. To do this, we need to create new LDAP credentials on the LDAP server of our PBX. This requires you to set up a username and password on Services/LDAP/Master. As a rule of thumb, configure a username that consists of a domain and a user part. Once you have completed the IT Advanced training, the reason for this will be obvious to you.
- Please configure a username like host.domain.net\dect
- Feel free to configure a password of your choice
- Activate the checkbox Write access.
Before we begin, please reset the device to factory settings by pressing the reset button until the LED turns orange. As a next step enter the IP address of your IP1202/IP1203 into your browser. The Install page is displayed. We recommend to add the gateway to your Devices app as you learned in your IT Connect training.
Afterwards, please set the Mode of your IP1202/IP1203 to Master. You can find this option on DECT/Config/Master. You have to reset the device afterwards.
As a next step, please go to DECT/Config/System and configure the following options:
- System Name: The system name must match the name of the DECT system object that we created in the first step .
- Password: This password has to mach the PBX password.
- Subscriptions: Due to security reasons please select With Activation
Press ok, afterwards a reset is required.
DECT IP-DECT master
As next step we will configure the IP-DECT Master. Please go to DECT/Config/Master
- Enable PARI function: Please select this checkmark
- Protocol: Please select H323/TLS for security reasons
- Gatekeeper: Please enter the IP address or DNS name of your PBX
Afterwards a reset is required again.
After the device is restarted, an authentication code is suggested under DECT/Config/System. As long as you do not press Ok again, the suggested authentication code will change every time you refresh the page. You need to write an authentication code in the configuration, so either just press Ok to accept the suggested code or choose an authentication code according to your liking.
Furthermore you will be able to enter a SARI now. Please go to DECT/config/SARI and copy the SARI you have purchased. You only need one SARI, even though you have multiple base stations.
In the next step we will complete the LDAP replication. To do this, please go to Services/LDAP/Replicator on your IP1202/IP1203. Set the following options, all other options should remain as they are:
- Enable: Please select this option
- Server: Please enter the IP or DNS Name of your PBX.
- TLS: Please select the TLS checkmark
- DECT Gateway Name: Enter the name of the DECT system object we created in the first step (Create a DECT System object)
- User: Please enter the username of the LDAP Server. This name should be configured like host.domain.net\dect
- Password: The password must match the password we configured when we were setting up the LDAP server
To add a radio to your DECT system, please go to DECT/DECT Overview/Radios. A list of all uninitialized radios in your network will be displayed. You should see at least one radio that belongs to the same device you are configuring. Just click on Add and then on OK. If you have more than one DECT base station in your network, you just add them the same way. If you need more than a few base stations, refer to our IP-DECT book and please attend our IT Advanced Training.
After a few seconds you will see the radio again, but this time it has a static registration, but is not yet synchronized.
To establish a synchronization between all base stations, one of the base stations must act as Air Sync Master. To do this, please go to DECT/config/Air Sync and set the Sync mode to Master.
After that, the LED lights up constantly blue.
When you put your DECT handset into operation for the first time, you will be asked for the subscription parameters. Please set the following options. If your device does not ask you for the subscription parameters, you can navigate to Menu/Connections/System/Subscription.
- System name: Please enter the system name here. The system name is the name of the DECT system object created in the first step. (Create a DECT System object)
- PARK: Please enter the PARK here. You will find the PARK on your IP-DECT Master DECT/User
- AC: Please enter the User AC here if you entered the IPEI already in the PBX. If this not the case, you have to enter the System authentication here. You can find the system authentication code under DECT/Config/System/Authentication code
- Protection: Set to No.
After you entered all the required options, your subscription will still fail. The reason is that we selected the Subscription mode With Activation while we configured the DECT system (DECT/Config/System). Although it would have made life much easier if we had selected the subscription mode Allowed, Allowed should not be used in productive systems as it is considered a security risk.
If you want to subscribe a handset when the subscription mode With Activation is active, you have to click on the IPEI before you start the subscription. You will find the IPEI under IP-DECT/User if you have entered the IPEI on the PBX user object in the previous step.
If the IPEI is not known, you must enter the IPEI of the handset as Anonymous handset under DECT/Anonymous. If you try to subscribe the handset, you must also press the IPEI in this case.
If the IPEI is already known in your IP DECT master, the IP DECT master will automatically register the handset with the PBX. If this is not the case, you must assign the handset to a user object. This is done by calling this number:
- Master ID: Since we did not change the master ID, the master ID is 0.
- User Number: The user number of the user to whom you want to assign the DECT phone.
- Access-Code: You must configure the user AC here. You can find the user AC on the DECT tab of the user object in the PBX.
An example for a number to be dialed would be this: *0*13*1234#
This number consists of 0 for the master ID, 13 for the user number and 1234 for the user access code.
After successful registration, you will see the DECT system name and the user name on the handset display.
- You can call any number now.
