Cisco 7940 Registration Problem

[dizzotinc]

I have two Cisco 7940 phones, and everytime I try to connect them, they register for the 60 seconds, and then they say Registration has expired. What is the problem?

Problem is that they should refresh registration just before expiration

 

[dizzotinc]

How do I set it up to do that?

By carefully studying your Cisco user/configuration manual. Set registration refresh interval to be from 1 to 10 minutes, as you like.
