If you do not have any Cisco-based call management server, the phone will work with Asterisk-based call management server. 

To get this to work, you will need the following: 

1. A known working SEPmacaddress.cnf.xml template.  I have a known working SEPmacaddress.cnf.xml for a 9971 (LINK) and it will have no problem working with a 9951.
2. TFTPd64
3. DHCP Option 150
4. Dial plan
5. Phone firmware

If you do not give us any specific information about your system landscape how would we be able to give you an answer on this?
