[VoiceOps] Calls Not Reaching Us

[Mary Lou Carey]

If you have a TDM network you should be able to call your SS7 provider 
and ask them to do a trace on it so you can see where it's dropping. 
Then you can call and put in a trouble ticket with the carrier. I always 
have the customer stay on the phone so you can do a 3 way call with the 
carrier. That way they don't have to talk about things they don't know 
and you can get to the correct people.
