Re: Echo between extension calls and extension and PSTN Calls

Hi

I have CUCm 6.0.1 installed and I am experiencing intermitent echo on calls between extensions and calls to the PSTN. Also i am having intermittent dropped calls with PSTN calls? Can you advise how to resolve these problems?

Check whether or not you are getting errors on the T1s for voice and data (if dialing between extensions). Check for errors on the controllers and interfaces. Path code and line code violations are not good when it comes to voice.
