7975 will not operate in Octal Line Mode

We have a 7975 phone with a 7916 attached that was mistakenly setup as a dual line phone when it was installed.  Once we discovered the error, we changed the phone to Octal Line in the CCA but even after a reboot the phone will still only handle 2 calls.

Below is the Show Ephone information for the phone (with the additional buttons removed)

ephone-2[1] Mac:E8BA.XXXX.XXXX TCP socket:[15] activeLine:0 whisperLine:0 REGISTERED in SCCP ver 17/17 max_streams=5 (tapi Client in ver 9/9)

mediaActive:0 whisper_mediaActive:0 startMedia:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:9 privacy:1

IP:10.1.X.X * XXXXX 7975  sub=1 keepalive 8029 max_line 32 available_line 32

Phone reports 32 Available Lines

button 1: cw:1 ccw:(0 0 0 0 0 0 0 0)

  dn 596 number 200 CH1 cc(03)   IDLE         CH2 cc(03)   IDLE         CH3 cc(03)   IDLE         CH4 cc(03)   IDLE         CH5 cc(03)   IDLE         CH6 cc(03)    IDLE         CH7 cc(03)   IDLE         CH8 cc(03)   IDLE

When I compare this information to another 7975 it looks almost identical except that my other phone does tno have the   cc(03)    after each channel.

What does this mean and could it be part of the problem?

I haven't seen this bug/problem before but I'd do a save config and reload.

reload the UC or the phone?

The UC. You can do it through CCA: Maintenance -> Restart/Reset...->Check Restart and click OK.

Deleting the phone and re-add fixes this issue.
