There are approximately 40 million copper wire communication connections 
still active in US. But the deadline for these to be  decommissioned is August 2 of 2022. 
Why is this important?

Because huge installation of  analog PBX system will  become obsolete, along with  alarm 
solutions and elevator  emergency communications which are not compatible with digital
communications. Business are looking for alternatives that won’t break the bank. They 
could be looking for you.
