Hello, I have a question more about telephony and long distance. A bit off topic, I know, but I hope someone will help me with it. When someone acquires a toll free number, they pay usually some long distance carrier to provide it. However, I would assume that the call from one end to another travels through several carriers, and the one that was hired by the customer will split the cost with others, right ? And also, calls coming from different geographical places may take different routes, through different carriers ? My customer's problem that they have a toll free number for faxing, coming into one of his land lines. Most of the calls coming in are OK, but for a few of his customers, the quality of the calls is too poor to be used for faxing. However the same customers seem to be able to fax him just fine if they don't use the toll free number. One of my thoughts was that his toll-free carrier may use VoIP for some segments of the network, and VoIP is known to have issues with faxing.
Thanks, Liviu
