I initially thought it could be a network issue from switches to CUCME gateway as the config was looking fine to me. I did a show ephone [...]
A paging number can be defined to relay audio pages to a group of designated phones. When a caller dials the paging number (ephone-dn), each idle IP phone that has been configured with the paging number automatically answers using its speakerphone mode. Displays on the phones that answer the page show the caller ID that [...]

This is the default behavior for all multiline IP phones. It may be desired that a particular line be selected whenever an outgoing line [...]

You can use an external TFTP server to off load the TFTP server function on the Cisco Unified CME router. This is also important if your router is not a high end router while the CME configuration is complex with many phones and expansion modules. Also Using flash memory or slot memory on the Cisco Unified CME router allows [...]
