Design Problem: Converting SMS to Voice Call

Postby leojc2 » Sun Mar 16, 2014 9:27 am

I am not a programmer and my telephony knowledge is limited.

We have this problem where a certain monitoring system (Let's call it A) can only send SMSes to pre-configured numbers (landline / gsm). This SMSes need to reach a response centre (Let's call it B) where its only means of communications is landline.

Schematically it looks like this:

[A] ---SMS---> ??? --- Voice Call--->[B]

The requirements include:
1. No human intervention, fully automated
2. Immediate, at most 1min for B to receive the call when a SMS is sent from A
3. Robust and reliable: works round the clock whole year round

Some constraints:
1. Do not use existing telco's sms to voice services

I am a mechanical engineer by training but was given this problem to solve for my organization. Is this something which Asterisk can be applied? If so what are the critical components?

Thanks alot everyone!

Text-to-Speech or TTS is the thing that you are looking for.First you will have to convert your sms content into audio file and then use asterisk to dial the landline and play out the converted audio file. If the sms content is only in english language then Asterisk Festival "" or Google TTS API "" can be used, otherwise for other regional languages you shall have to search for that particular language TTS support.
Just Google Asterisk text to speech support for multitude of other options :)
