Your Comcast digital phone service should work with both landline and cordless phones. However, cordless phones tend to have more issues than landline phones. For example, interference issues are common with a cordless phone. You can troubleshoot problems with your cordless phone yourself, or contact Comcast for assistance. Your cordless phone can also cause interference. For example, using your cordless phone can interrupt your Comcast Internet service. A Comcast service technician can come to your home and troubleshoot interference problems between your Comcast digital phone service and Comcast Internet service.
