Call list synchronization CRM/BCM

Hi all,

I can't get my call list to be connected and synchronized in BCM.

1- I created a campaign with "Phone" activity

2- I created a call list

3- I can activate "manual" call lists (in execution mode)

4- I can switch to "automatic" but then I cannot activate the lists. The following error message appears : "Maintain the dialer information in call list C-00000020"

Where can I enable this functionality? RFC connection was defined and inbound calls are working and coming through CRM.

Many thanks,

Eli
