Answering incoming calls while a call is in progress

[ryan.boles]

I need to know if Cisco Unified CM version 7.1.5 has the capability to allow a user to place a call on hold that is in progress so that user can answer an incoming call.  (In other words have a call in progress and be able to answer a second call that comes in while still on the first call).  If it does have the capability can someone please indicate the steps to take to enable this function.

Thanks!

Hi ct0000002, 

This would be configured under the specific line on the phone.   

Device -> Phone -> Find Phone -> Select Line on the phone -> Scroll to the very bottom of the page. 

Multiple Call/Call Waiting Settings on Device 

Note:The range to select the Max Number of calls is: 1-200
Maximum Number of Calls
Busy Trigger	(Less than or equal to Max. Calls)

Maximum Number of Calls

You can configure up to 200 calls for a line on a device, with the limiting factor being the total number of calls that are configured on the device. As you configure the number of calls for one line, the calls that are available for another line decrease. The default specifies 4. If the phone does not allow multiple calls for each line, the default specifies 2. For CTI route points, you can configure up to 10,000 calls for each port. The default specifies 5000 calls. Use this field in conjunction with the Busy Trigger field. Note    Although the default specifies 5000 calls for maximum number of active calls that can be configured on a CTI route point, Cisco recommends that you set the maximum number of calls to no more than 200 per route point. This will prevent system performance degradation. If the CTI application needs more than 200 calls, Cisco recommends that you configure multiple CTI route points. Tip    If you use the external call control feature, and the policies on the policy server dictate that a chaperone must monitor and record calls, make sure that you set the Maximum Number of Calls setting to 2 and set the Busy Trigger setting to 1. Tip    To review how this setting works for devices with shared line appearances, see topics related to shared line appearance in the Cisco Unified Communications Manager System Guide.

Busy Trigger

This setting, which works in conjunction with Maximum Number of Calls and Call Forward Busy, determines the maximum number of calls to be presented at the line. If maximum number of calls is set for 50 and the busy trigger is set to 40, incoming call 41 gets rejected with a busy cause (and will get forwarded if Call Forward Busy is set). If this line is shared, all the lines must be busy before incoming calls get rejected. Use this field in conjunction with Maximum Number of Calls for CTI route points. The default specifies 4500 calls. Tip    To review how this setting works for devices with shared line appearances, see topics related to shared line appearance in the Cisco Unified Communications Manager System Guide.

Hope this helps,

Justin
