How to verify if Telco PRI E1 is working from my Voice Gateway.
Posted on 2014-07-10
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
