1 FLX VoIP Registering the FLX with Siemens HiPath 4000 & OpenScape Voice Server April 2 nd, 2012 This technical note gives a detailed description on how to register a Revolabs FLX conference phone with Siemens HiPath 4000/OpenScape Voice IP PBXs. On the Siemens HiPath 4000/OpenScape Voice servers a SIP extension and user has to be created using Siemens tools. Once that user is created, the FLX can be set up to register with the Siemens IP PBX. This document does not outline how to create a user on the PBX. Creating users on the Siemens PBX requires administrative rights. We recommend that a trained Siemens IP PBX administrator perform these tasks. Configuring Siemens HiPath 4000/OpenScape Voice for FLX Registration To prepare the FLX Conference phone several steps will have to be performed. These steps are the same as those required for any third party SIP device. Login to the Siemens HiPath 4000/OpenScape Console Create a directory number Add a user Add the FLX device Associate the FLX with the user To configure the SIP endpoint start the Setup Wizard Telephones / Subscribers-> IPTelephones in the Siemens HiPath 4000/OpenScape GUI.

2 For FLX endpoints set the Type field to SIP Client. The other data can be adjusted as you need, including the Callno and the Name. Please provide the appropriate License Type. With the data entered in the overview table a FLX endpoint can now register without authentication. For safety reasons it is recommended to activate authentication for every FLX (SIP) endpoint in the system. To do this, press Edit to enter the Change Station page for the specific Callno. In the screen that opens, check the box Authentication active and enter a Password, a SIP User ID and the Realm. Please use non-trivial passwords. While the Realm must be present in the setup on the Siemens switches and is predefined with a default string, the FLX is not using this information.

3 The SIP User ID MUST be present and is a string which is used during the authentication process. This could be, for example, the call number of the FLX endpoint with a prefix. You have now created the directory number, user, and the phone device and have associated them with each other. You can now register the FLX with the Server. Testing of the Revolabs FLX phone has been done on Siemens HiPath 4000 and Siemens OpenScape Voice servers configured for TCP traffic. In our testing it has been noted that if the Siemens PBX is set up to accept TCP and UDP devices, this caused issues with the registration and call handling. We therefore recommend using the Siemens PBX only with one type of transport protocol, preferably TCP. Registering the FLX with the Siemens HiPath 4000 & OpenScape Server Please use the FLX web UI to register the FLX with the Siemens OpenScape Voice. 1. IP address of the FLX. a. If you are using DHCP in your environment, the FLX automatically receives an IP address. From the FLX handset, choose Menu and System Info (the symbol with the i ) and select About System. The IP address (static or via DHCP) of your FLX is shown. b. If you are using static IP, on the FLX handset chose Setup (the wrench symbol), Advanced Setup, enter the administrator password (default password is 7386 ), enter Network Settings. Change DHCP ON to DHCP OFF. Then enter IP Settings. In this menu you can enter the IP address, Subnet Mask, and other relevant information. Once you have entered all information, select Return, and in the Network Settings menu select Load Settings. This will restart your phone with the new network settings. 2. In a web browser of your choice, enter the IP address of the FLX phone. This will open the web interface for FLX. Enter the password ( 7386 ), and select Administrator in the right top of the screen. 3. On the left side, select SIP Registration. The following screen will show:

4 4. Enter the registration info for your OpenScape Voice: Registrar the Siemens HiPath 4000/OpenScape Server IP address, in our example ID User ID for the User added to the Siemens HiPath 4000/OpenScape server, in our example 700 Display Name this can be any friendly name for the user Username enter the same User ID as above Password the End User s password set in the HiPath 4000/OpenScape Voice server 5. Press Save. You will see the following screen.

5 6. On the left, select Transport. 7. For the TCP/UDP selection select the transport protocol you are using. We recommend not using Both TCP and UDP with the OpenScape Voice, but either UDP only or TCP only. 8. Press Save. 9. On the left, select SIP Configuration. 10. For the DTMF Signaling method, select SIP INFO. 11. Press Save.

6 12. On the left side select Restart, and click on the Restart button. Your FLX phone will restart. You can close the Web browser. If registration is successful, the handset will show the user ID at the top of the home screen. If there is a registration failure, the handset will show that the phone is not registered. Please verify that the user ID and password are the same as the ones specified when configuring the Siemens HiPath 4000 /OpenScape server. Also, in the Siemens HiPath 4000/OpenScape Voice server confirm that the device was correctly set up and associated with the user.
