MBG Engineering Guidelines, Release 8.0
Figure 6 shows one sample configuration that could be used. IP phones that are to be recorded are on the same
LAN segment as the MBG server. DHCP is enabled in MSL, and MBG provides DHCP configuration such that
the sets use the MBG server as their TFTP server and as their ICP. MBG then proxies the set registrations to the
real ICP on the other segment. Sets on a different LAN segment using the MCD DHCP server connect directly to
the MCD and are therefore not recordable.
As an alternative to changing the network topology, each set that should be recordable can be individually
programmed to connect to the MBG. Hold down the “7” key and put each set into Teleworker mode. At the
prompt, enter the IP address of the MBG.
MBG servers can be chained together to allow recording of remote teleworker phones. Figure 7 below shows an
example of a teleworker set connecting through the edge MBG to an MBG server for call recording (and finally to
the MCD), so that it can be recorded along with the sets on the Recorded LAN. To configure this scenario, an
“ICP” entry is added to the edge MBG containing the IP address of the LAN MBG used for recording. All remote
sets that should be recordable must be configured with that “ICP”. The recording MBG will then proxy the remote
sets to their real ICP.
