In the medical and emergency support field, many doctors and technicians are receiving their information on their cell phones instead of using alpha pagers, digital pagers, or landlines. Many doctor and technicians are using text messaging to receive their emergency calls. Receiving the information via text allows the doctor or technician to properly triage the call. For example: If a doctor or technician is driving they can pull over and read the message instead of having to answer a ringing phone. Another example would be an electrician who is in the middle of an install can wait a few minutes to finish the job and then check the text message. If the text comes in very close together the doctor or technician can take care of the more important calls first instead of getting delayed by verbally taking the message.
Not all answering services have the ability to text via the SMS (Short Message Service) protocol. The SMS protocol allows for the end-user to reply back that they got the message. The reply back feature is useful for doctors or technicians that require that the answering service confirms receipts. Once the end-user receives the message they reply back that they received the message the answering service then receives a message on the end-users account that confirms receipt. The SMS feature to cell phones is quickly becoming a favorite means of communication in the answering service industry due to its accuracy, reply back ability, and reliability.
