Issues with IP phones registering with wrong call manager on network

[djswaine1]

Can anyone assist me in answering this issue. We have 3 call managers and in three remote locations, all ip phones on the network are registering with a single call manager and not the local call manager in each area. Suggestions?

I don't know the exact sequence of things but it ain't that complicated.

The phones ask the DHCP server for a TFTP server address (option 150). On the TFPT server the phones hope to find a config file.

So you need to find out what is the DHCP server for each location and use the TFTP server option to point the phones to the righ callmanager.

Cheers,
