If you pick up your land line and there is no dial tone on it, be patient before calling your phone service company to come over and fix the problem. You can first check if you can solve the issue yourself by doing a little troubleshooting. It can help you find out if the problem lies with the provider’s equipment, or if your phones or phone jacks are not working properly. Majority of the phone companies are just accountable for repairing their equipment outside your house. However, if you have a maintenance agreement signed to get repairs inside your home then it is possible. By checking yourself you can fix a faulty jack, or calling an expert to get the job done.
