Hello Everyone, I am looking for an app which when receiving an SMS will act like a beeper or pager and make a repetitive sound or prolonged sound . I am a physician and I have installed a VOIP in my office which will send me both a text message and an email if the matter is urgent . However, if I happen to miss the single notification sound of an incoming message, I could miss an urgent situation. Moreover , if I am sleeping , I would like a notification sound which would wake me up . I would also like it to call back periodically until I someone how acknowledge that I got the message. Maybe I would be required to press a "dismiss button' or else the notification tone would continue to repeat. Finally, I would like the app to specifically recognize the source of the sms , ie my VOIP system , so that every sms I receive does set off the urgency notification sound . I have looked I the App store under pages and beepers but it is unclear to me if the apps I looked at have this capability . Does anyone know if such an app exists? Thanks for your help.
