We are experiencing a problem with an analog line at one of our buildings. It is intermitant and only appears to be happening on the first line in the hunt group. Before an incoming call from the pstn hears a ringback, the caller hears a loud grinding noise. This noise can continue into the call being answered. It disappears after a few seconds. If we disconnect the line from the gateway and plug directly into an analog phone, we cannot duplicate the problem. Verizon has been out and can find no problem with the line. It is looking more and more like either a configuration or ios problem. The gateway is a cisco 1760 (h.323) running c1700-sv8y7-mz.124-15.T1.bin
We have another gateway running this same ios and it is not experiencing the problem.
Has anyone else seen this problem?
