CUCM 7.1.5 - IP Phone 7962, If call is being forwarded to a mobile number, the history of the calls is not seen in the IP phone and on the mobile phone only the PSTN number of the IP Phone is seen, so if there is a missed call in the mobile, we are not able to check who has made the call becuse only IP phone PSTN number is displayed as missed call and who actually called is not know, how do we find that or what options are do we have to enable on the IP Phone and CUCM to get to call forwarded history on the IP phone.
