DND ON,
Thanks for the ideas and your time!
I changed the TN/DID to DISA and was able to dial outside lines and extensions. However when I dialed the page extension, I heard four "beeps" then the steady dial tone returned. I was able to dial an extension after the steady dial tone returned. Not sure what is happening.
DISA is something the company hasn't used, and I didn't have to dial a password, yikes. I changed the DISA back to single in the Call Routing Table and read the manual a bit. DISA would take a bit more reading and configuration for it to be safe.
I did figure out another way to test the paging system. The paging system has a ring tone generator connected to an extension, so I set the TN in the Call Routing Table to the extension for the ring tone generator. It works...
Thanks,
Jeff
