10.0pt;font-family:Arial;color:navy'>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>

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>

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>

<br>
>From my quick perusal of the docs it seems this is probably impossible<br>
but I will throw out the question to see if I have missed something:<br>
<br>
Can a single 7960 phone talk to two separate call managers and <br>
present two lines, one from each system? Not two CM's backing each other<br>
up, but two distinct call manager systems? <br>
<br>
If so how do I work this magic?<br>
<br>
Thanks for any pointers<br>
