I'm fairly new to CUCM and was looking for some guidance. I recently inherited CUCM 10 and have gotten the basics down, but am still learning the rest.
There is an external 1(877) number (OpenVoice Conference Number), and is the only 877 number we cannot call. When we dial it, there is only silence and then the call automatically ends. I am able to call the number from my cell phone, so I know it's a working number. Here is the list of our call routes for 18XX numbers.
As you can see, there are some routes that are made to refuse the call. I made a route that is specified for the number (See "Conference Call Number" in the picture), and am still not being put through. But when I dial other 877 numbers, I have no issue.
I tried to use DNA, and although I'm not entirely sure that I am putting the information in correctly, these were the results:
I've contacted our phone service provider and opened a ticket with them to make sure that the number isn't dropping on their end.
Any help would be greatly appreciated as I'm a little lost on what I could be doing to fix this.
