Hello: I work for a CLEC that provides copper trunks and internet connection to a local customer here. They have a small 2 year old Samsung key system connected back to the home office via a static IP over the internet. 3 digit dialing between sites did work at one time. Having one way dialing issues now. Local site can call any extension at the home office just fine. However the home office cannot call back this way (To any extension) most of the time, get busy signals. The customer is unhappy the vendor is pointing fingers at the CLEC. Any thoughts what might be causing this issue or the best way to trouble shoot it? Thanks in advance.
