We've been having ongoing issues on a CIX670 system. When calling into the main PRI number at our office, callers frequently get static once the call is connected (can't hear the greeting), or they'll get a fast busy, or they'll get disconnected after a several seconds, without ever reaching the system greeting. The phone company ran intrusive testing for 2 consecutive nights on the PRI, and found no errors. Could the phone system be causing these issues, and not the PRI? Is there a way to check with emanager? We already had a service tech check and say he didn't see any problems with the system. The system was power cycled already but did not help. Thank you in advance.

Please disregard this post, we narrowed it down that it's not an issue with the phone system, since it's happening when calling out to other numbers.

The outbound calls still go thru the PRI card in your PBX. The service provider tested to the NIU or a CSU in front of or in your PBX. My take is it might be a wiring issue between your PBX & the service providers D-MARC, or the PRI card in your PBX. Your vendor could troubleshoot this.
