# Selecting Sets to Record (Direct Call Recording)

DHCP setups vary according to the percentage of total sets that you want to record.

To record… | You can use this DHCP setup…
A small percentage of total sets | Configure the phones manually as teleworker phones and enter the IP address of the MBG/SRC server when prompted for the Teleworker Gateway IP address. For more information, refer to the MBG Remote Phone Configuration Guide available at Mitel OnLine.
A large percentage of total sets | A possible setup for this scenario is to deploy the recorded group on a different subnet from the non-recorded phones. You can use the MiVoice Business/3300 ICP as the DHCP server for the non-recorded phones and the MSL server as the DHCP server for the recorded phones subnet. The recorded phones will then receive the IP address of the MBG/SRC server as their Call Server (ICP) and TFTP addresses.
All sets | Configure the DHCP server in your MiVoice Business/3300 ICP to supply the IP address of the MBG/SRC server to the phones as their ICP and TFTP addresses OR Enable the pre-configured DHCP server supplied with the MSL server.

For more information about configuring DHCP in the MSL server, refer to the "Configuring the Server" section of the Mitel Standard Linux Installation and Administration Guide.
