IP Phone not registering

Hi Community

 

I registered an IP Phone 7841 in one of my call manager and it worked, but that brought me problems because there was no license for that model so I had to delete and restart the application to overcome the error. So far so good.

Now I am trying to register in another call manager who has license for that model only he does not register the phone

any idea why?

there is a Sip trunk between the two call manager's
