Hello,
we are using a c6921 (SCCP-9.2.1.0) with CME 8.6. If you make a call, press hold and try to make a new call, a message
about no channels availabled is shown. It is strange because if you make a call, press transfer button, then you can make a new
call without problem. Besides you can receive serveral calls and use hold feature without problem. Release 9.2.1.0 is supposed
to support multi-call per-line appearance. Is it a bug or normal?
That the CME configuration:
ephone 59
device-security-mode none
mac-address C464.13FD.E381
max-calls-per-button 2
type 6921
button 1:59
!
Thanks in advanced.
Regards

I'd suggest upgrading the firmware to 9.4.1 and see if the behavior is any different. I don't have a 6921 in front of me to test with.

Hello,
I have also found the following bug CSCtq45335
The 6921/6941/696/6945(SCCP 9-2-1-0) cannot make a call with off-hook.
the massage "Unable to create a call; the maximum number of calls for this line has been reached..." popped up
reproduce steps:
1. Dialed number with on-hook.
2. Off hook
3. can not make a call, I can see the dial-tone.
Conditions:
Only occurred on 6921/6941/696/6945 SCCP 9-2-1-0
Workaround:
In CUCM 8.6 and later, configuring maximum number of calls to 3 under phone's line page can avoid this issue. Prior to CUCM 8.6 there is no workaround available.
But how configure number of calls to 3. Using max-calls-per-button 3?. But if i try a get an error saying
that for 6921 max is 2.
Thanks,

I have done tests and the issue is not associated to a firmware version. I have used serveral firmware for the phone a serveral version for CUCME (8.6 and 9.1). If you try to do a transfer you can make a new call. The issue is only associated to hold feature. I think that the phone by default set the maximun call per line to 1 but there is no way to set this value greater that one. The command "max-calls-per-buttton" has no effect. I have also reproduced the issue using sip firmware.
There are more peaple with the same problem:
