Thanks for all the suggestions on testing line voltage, getting the phone company involved, etc.
Unfortunately we haven't been able to schedule a service call with the customer yet, and are hoping to have some kind of interim solution to put in place next time we visit. The problem may take some time to clear up if the phone company has to be involved, and the customer is quickly losing his patience since the complete replacement of his KXT-624 did not solve the problem. Does anyone know of any devices that can detect an incoming call and generate a full ring, whether or not the incoming call signal is interrupted or weak? We're hoping to install such a device between the verizon NID and the KXT-624 on all incoming lines, hoping that it will cause the system phones to ring normally instead of clipping off when the verizon line voltage fails (assuming that is the problem). Thanks again, Rob H. _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
