7960 will not allow Call Forward All from device or CUCM

[James Gladwell]

CUCM System version: 8.6.2.20000-2

Phone is a 7960

When the user tries to setup call forwarding on the device for after hours coverage, there is a voice prompt saying "The call cannot be completed as dialed" before he is finished entering the number to be forwarded to.

When I try to go into the DN configuration page in CUCM and set the number to forward to the desired number, it sets the forward without any error message in CUCM, but when I call the extension from my cell phone, it never gives a ringback, so I don't think it is actually trying to do anything.

I have deleted the phone from the system, let it boot back up and pull an "Auto 2xxx" number, then reconfigured the original DN.

There are no other devices with this DN on it.

I configured that DN on 7925 for him to carry around overnight tonight, and I will have to fix it before the weekend.

I am not very experienced with CUCM/ Cisco VOIP but am now "the man" due to terminations and resignations lately. 

What would cause this??

Hi James,

Please check as below:-

1). Call that number directly before setting it as forward number and check if you are able to dial it or not.

2). If you are not able to dial then check the partition and CSS, whether that phone has got the access to call that number.

Hi James,

Just to add a note to the good tips from Nishant here (+5 )

In CUCM there are "dial restriction" levels that you can use to allow or

restrict where users can call based on their CSS (calling search space)

This restriction level CSS can also be applied to the Call Forward capabilities

as shown below & is likely where your problem lies.

This requirement for different levels of "restriction" for Call Forward All

can be controlled by using the Call Forward CSS(calling search space)

as detailed below

# Call Forward and Call Pickup Settings
# Calling Search Space Activation Policy	# Three possible values exist for this option: # •Use System  Default # •With Configured  CSS # •With Activating  Device/Line CSS # If you select the With Configured CSS option, the Forward All Calling Search Space that is explicitly  configured in  the Directory Number Configuration window controls the  forward all activation  and call forwarding. If the Forward All Calling  Search Space is set to None, no  CSS gets configured for Forward All. A  forward all activation attempt to any  directory number with a partition  will fail. No change in the Forward All  Calling Search Space and  Secondary Calling Search Space for Forward All occurs  during the  forward all activation. # If  you prefer to utilize the combination of the Directory  Number Calling  Search Space and Device Calling Search Space without explicitly   configuring a Forward All Calling Search Space, select With  Activating Device/Line CSS for the Calling Search Space Activation Policy.  With this option, when  Forward All is activated from the phone, the Forward All  Calling  Search Space and Secondary Calling Search Space for Forward All   automatically gets populated with the Directory Number Calling Search  Space and  Device Calling Search Space for the activating device. # With  this configuration (Calling Search Space Activation  Policy set to With  Activating Device/Line), if the Forward All Calling Search  Space is  set to None, when forward all is activated through the phone, the   combination of Directory Number Calling Search Space and activating  Device  Calling Search Space gets used to verify the forward all  attempt. # If  you configure the Calling Search Space Activation Policy  to Use System  Default, then the CFA CSS Activation Policy cluster-wide service   parameter determines which Forward All Calling Search space will be  used. If the  CFA CSS Activation Policy service parameter gets set to  With Configured CSS,  then Forward All Calling Search Space and  Secondary Calling Search Space for  Forward All will be used for Call  Forwarding. If CFA CSS Activation Policy  service parameter gets set to  With Activating Device/Line CSS, then Forward All  Calling Search Space  and Secondary Calling Search Space for Forward All will be   automatically populated with the Directory Number Calling Search Space  and  Device Calling Search Space for the activating device.
#	# CFA CSS Activation Policy Service Parameter # Ensure  the CFA CSS Activation Policy service parameter that  displays in the  Clusterwide Parameters (Feature - Forward) section of the  Service  Parameter Configuration window is set correctly for call forward all to   work as intended. The parameter includes two possible values: # •With Configured  CSS (default) # •With Activating  Device/Line CSS # When  the Calling Search Space Activation Policy is set to Use  System  Default, the value of the CFA CSS Activation Policy service parameter   gets used to determine the Call Forward All CSS. # When  the option With Configured CSS is selected, the primary  and secondary  CFA Calling Search Space get used. When the option With Activating   Device/Line CSS is selected, the primary and secondary CFA Calling  Search Space  get updated with primary line Calling Search Space and  activating Device Calling  Search Space. # By default, the value of the CFA CSS Activation Policy  service parameter is set to With Configured CSS. # See Service Parameters  Configuration for information on accessing and configuring service  parameters. # Roaming # When  a device is roaming in the same device mobility group,  Cisco Unified  Communications Manager uses the Device Mobility CSS to reach the  local  gateway. If a user sets Call Forward All at the phone, the CFA CSS is  set  to None, and the CFA CSS Activation Policy is set to With  Activating Device/Line  CSS, then: # •The Device CSS  and Line CSS get used as the CFA CSS when the device is in its home location. # •If  the device is  roaming within the same device mobility group, the  Device Mobility CSS from the  Roaming Device Pool and the Line CSS get  used as the CFA CSS. # •If the device is  roaming within a different device mobility group, the Device CSS and Line CSS  get used as the CFA CSS.
# Forward All	# The  settings in this row of fields specify the forwarding  treatment for  calls to this directory number if the directory number is set to   forward all calls. The Calling Search Space field gets used to validate  the  Forward All destination that is entered when the user activates  Call Forward All  from the phone. This field also gets used to redirect  the call to the Call  Forward All destination. # Specify the following values: # •Voice Mail—Check  this check box to use settings in the Voice Mail Profile Configuration window. # Note When  this check  box is checked, Cisco Unified Communications Manager  ignores the settings in the  Destination box and Calling Search Space. # •Destination—This   setting indicates the directory number to which all calls are  forwarded. Use any  dialable phone number, including an outside  destination. # •Calling Search  Space—This setting applies to all devices that are using this directory number.

And beautifully explained by one of the very BEST, Hailey from CNC here;

Thanks guys.

I had to give it the correct CSS under Call Forward and Call Pickup Settings for "Forward All" and it now works.
