I have a CUCM with release 6.1.2.1002-1. I also have a calls recorder (Asterisk).
I did a trunk betweeen my CUCM 6.1.2.1002-1and Asterisk. I configured on CUCM the monitoring and recording feature.
For that I configured a recording profile and I enabled the in Cisco IP Phones and on the lines (DN) I configured the Recording Option, Recording Profile and the Monitoring Calling Search Space.
The recording of calls works fine but I have a problem. When I have incoming calls from PSTN I can not see the original calling number and when I do outgoing calls to the PSTN I can not see the called number.
