<DIV><FONT face=Arial size=2>We have three clusters working on the same network
and have not run into any problems. (Thank goodness). We do, however, only have
one DHCP server running which tells phones by default to point to a particular
TFTP server depending on the network the phone is on. By modifying option 32 on
the phone to yes and then option 8 to the appropriate TFTP server, things have
worked tickety-boo. </FONT></DIV>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">My understanding is
that CCM clusters should not co-exist on the same network and therefore
multiple lines from different clusters is not a supported feature of the
phones. We have this problem in our small enterprise, where there is one
network segment and 2 (sometimes 3) CCM clusters, and one DHCP server with the
TFTP option enable for only one of the CCMs. <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">In order to switch
CCMs, I just have everyone switch the TFTP settings on the phone as suggested
below. But sometimes even this doesn’t work. The Device information is cached
in the phones and even when I erase the configuration, disable DHCP, and
modify the TFTP setting, the phone will connect to the wrong CCM. Only by
temporarily disabling the TFTP service on the wrong CCM, am I able to connect
to the right one.<o:p></o:p></SPAN></FONT></P>

different times? If you need at different times, than yes, you can use
alternate TFTP settings for this. If you need them at the same time, than I'm
pretty sure you cant. If you need a phone with a lines from different
CallManagers, I would suggest getting a business style analog set with
multiple line support (some support up to 8) and plug these into FXS ports on
the different CallManagers.</SPAN></FONT><o:p></o:p></P></DIV>
