When I checked in Cisco RTMT about why some phones with same models are working and other phones with exactly same model are not working I found that from call manager it is only sending invite messages that's it. I do not understand why this is happening. Please see below screen shot from RTMT. In perfect environment when phones are working fine it should be like this.
But when phones are not dialing out it is showing as
10.212.1.10 is the CUCM and 172.16.1.5 is the CUBE router.
