8945 Phone: Place call on hold and make a new call?

[gmgarrian]

Does anyone know if it's possible on an 8945 phone to place an active call on hold and then make a new call while the first call is still on hold?  The phones in question only have a single line button configured with a DN.

Also, they're registering to a CUCM 8.6 server.

I found this but it doesn't specify:

Thanks!

Wrong forum, try "IP Telephony".

Don't know about 8945 but for 79xx phones you can configure this behavor by specifying the number of calls in dn configuration in UCM.

Sorry for the wrong forum.  This turned out to be a phone firmware issue caused by a bug:

Per TAC:

Seems you are hitting is this bug CSCtq94796:

Unable to place 2nd call from same line appearance on 894x phones  

Symptom:

When an active call is placed on hold and the user presses the New Call key they get the following message.

"Unable to create a call, the maximum number of calls for this line has been reached."

This is by design. Features supported are the following:

Maximum calls is hard-coded to 3. Busy trigger is hard-coded to 2. When there is no call on the line, the user can make or receive a new call. When there is one call on the line, the user can make a consult call or receive a call. When there are two calls on the line, the user can make a consult call.

What they can't do is put a call on hold and press New Call.

Conditions:

8941 or 8945 on CUCM 7.1.5 and higher running firmware 9.1(2) or 9.1(2)SR1.

Workaround:

None. Firmware 9.2(2) due out Oct 2011 will change the behavior of the phone so this no longer occurs. Maximum calls/Busy trigger will be changed to 24/24 and configurable.
