Earlier this week I went to use my phone and I couldn’t dial out, I called the telephone company and they dialed my number but I didn’t ring. So a technician came out to troubleshoot. They discovered that my phone line was mixed with my dedicated fax line, and fixed that issue. They also discovered that the problem was caused by my security system phone line. They told me to call the security company. The security person came out and fixed the other issue but blamed it on the telephone company. I didn’t want to play the blame game and thanked everyone. All is working again, but what really caused the problem?? Someone knows, not me.
