I have a customer who was complaining of callers not being routed to extensions after AA answers. (AA is on all the time). They also said there were squealing noises on the lines sometimes. When I got to their office, I noticed the VS 5 light was off. All the other modules seemed fine. I pulled out the VS 5, did some test calls and was able to answer the calls and get dial tone out etc.
I tested the VS 5 back at my lab and squealing sounds alright! more like screeching. So, I ordered them a new VS 5 which is on its way.
Meanwhile, the customer emailed me this morning, they are not able to answer calls they are getting dead air, also they are unable to get dial tone to dial out.
Is this the processor now going out too??? Could it be the back plane/carrier that is wreaking havoc?
thanks!!
