Hello,
So first I'm going to give a disclaimer: I'm not a voice guy, but apparently, I'm the only person on my team who's skilled in the art of google and reddit-fu.
There is an ongoing issue at one of our clients sites where an analog paging system (viking) is not functioning. The paging system connects using an anlaog line to an FXO port on a 2851 router. What happens is we make a call, CUCM successfully routes it to the ISR, and the voice port goes off-hook, but no audio is heard over the paging system.
At this time, we have replaced the and a tech has been dispatched to verify the state of the paging system and the telecom cabling. I think the paging system itself has also been replaced. The only thing that hasn't been tested, is the portion of the analog line that is patched to the FXO port itself.
We're thinking that a tech will have to be dispatched again - preferable a different one than last time (as there are some concerns about the integrity of their work), but before we do that I thought I might as well try to get the internet to weigh in on this...
Here are the voice configurations on the router if you're curious:
