Thank you for your reply. on the MX3300, in form "Multiline IP Set Cong ", I have the 5010 setup.
I tried testing the connection internally, and still didn't work.
the IP address for my MX3300 is 192.168.0.10.
so, I put that address 192.168.0.10 on my 5010 in TFTP and RPC settings.
afterwards, I tried putting static addresses for the phone itself 192.168.0.253, and it bootup, with no RPCS error. However, it just hung on the address 192.168.0.253
Is there something I need to still configure on the MX3300 ?
thank you
