Hi,
I need to connect Cisco 6921 phone on asterisk, but I am unable to convert it to SIP.
I am trying to update phone to SIP following this instruction and downloading the last firmware (also tray with 9.2)
http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/6921_6941_6961/firmware/9_1_1/english/release/notes/6921_911.html#wp193731
the phone firmware is SCCP 9.1.0 -> unable to update to SIP
update to latest SCCP 9.3 go ok! i also try to update form this version to sip but also nothing!
We try on separe network on DHCP we add option 66 and 150.
TFTP local computer
DO I need to press some key? #1234567...??
Did somebody manage to covert it to SIP without CCM?
THX,
IVan
