1. Automatic Configuration Server discovery - using Multicast DNS

The easiest way of providing 6900 phones with the address of the MiVoice Office Application Suite is using the Multicast DNS auto discovery (by default, this is enabled on the MiVO App Suite v5.1.14 or later). If the phones
are not provided with a DHCP option then they will perform an 'Auto Discovery' to find the configuration server.


With Multicast DNS a method of providing IP address and other basic networking information to the phones is still required and will usually be DHCP. Multicast DNS is used only to supply the Configuration
Server address. If the DHCP server provides any Vendor/PBX specific options (e.g. 43, 66, 125) then the phone will not attempt to discover the configuration server by Multicast DNS. Either remove these settings from the
DHCP server or use method 2 with DHCP.


If there is more than one MiVoice Office Application Suite on the network, the phone will present a list of auto discovered servers for the user to choose between.


Once the phones have been provided with the address of the MCS server, they will contact the server and the registration process (and any firmware updates) will begin. The phone will reboot a number of times during this
process. The phone will now be registered with the MCS server and display a red Setup screen shown in the
next section.

2. Automatic Configuration Server discovery - using DHCP (with Vendor/PBX specific options)


If the phones are on a different subnet to the server, DHCP can be used instead. Please review the section below if DHCP is being used paying specific attention to the information on removing options 43 & 125.


DHCP Configuration


If using DHCP to provide the phones with the address of the MCS server, it is recommended that the following
DHCP options are used:


Option 66 for the 6900 SIP phones
Option 128, 129 & 130 for the 5300 Series MiNET phones


Using these DHCP options will allow 5300 & 6900 phones to work alongside each other on the same network using the same DHCP server.


Configure Option 66 in your DHCP server with the IP address of your MCS server.


For specific information on configuring the MiVoice Office 250's built-in DHCP server, please refer to the 'MiVoice Office 250 DHCP Configuration' section.


When using option 66 on a DHCP server, it should be configured as an ASCII parameter containing an IP Address (not an IP Address parameter). This includes the built in DHCP server of the MiVoice Office 250.


The 6900 Handsets will also pick up the following DHCP options and use them as the configuration server
address (in the order listed):


43, 159, 160, 66


If any of these options are already in use on the DHCP server then it will overwrite the configuration server used on the handset and could stop it working. One possible source for causing a conflict is DHCP
options for 5300 phones using option 43/125. These can be changed to use the preferred options 128,129 & 130 to avoid conflict.


Remove options 43 & 125 from the DHCP if they are there so that the 6900 phones do not pick up the phone system's address.


Once the phones have been provided with the address of the MCS server, they will contact the server and the registration process (and any firmware updates) will begin. The phone will reboot a number of times during this
process. The phone will now be registered with the MCS server and display a red Setup screen shown in the next section
If you have this continue to the Initialising Handset section.


Most common Incorrect Configuration


If the phone displays the following screen instead of the red setup screen, it has connected to the MiVoice Office 250 via MiNET.

If this happens, the phone has not been passed the IP address of the MiVoice Office Application Suite and the DHCP configuration is incorrect. Once the DHCP configuration has been fixed, restart the phone. DO NOT
enter a PIN at this point.
