I have a issue with my telephone system, I am unable to place or receive receive any call. I have forwarded the issue to my Telco and they just performed the loop test and confirm that it is working from there side. Can someone advise for a steps on the terminal to verify that the router is working perfectly and Telco has issue on there side. I have the following setup:
- PRI E1
- Cisco 2800 series

E1 0/0/0 is up.
Applique type is Channelized E1 - balanced

I am suspecting an issue with the PRI connection and I wanted to confirm and forward it to my Telco. Let me know if you need me to run any terminal commands. Thanks in advance.
