CISCO IP phone upgrade firmware

Filed under: Tech articles — admin @ 4:00 pm

 Cisco ip phones can support several voip protocols:
 SCCP, H.323, SIP, MGCP. 
I had upgraded one cisco ip phone 7905G from H.323 to
 SCCP to adapt CCME. 
 Note the below steps when you upgrade your ip phone.

1.Download correct version firmware to
 your TFTP root directory 
2.Add and edit the default configuration file 
XMLDefault.cnf.xml. The following file is default format:
