I have a customer who is going around and around with a fax vendor as to why they cannot fax. Vendor has replaced cards , cables etc. Vendor sez telco trouble telco sez no way. Now they want me to intervene and give them an honest diagnosis and opinion. I need to find a 1000hz test number to measure the loss with an old TTS 28. Perrysburg Ohio is the site but any dial up number would help. Thanks in advance.
