i am in the process of setting up a hotline where people can call in to hear a 5 minute pre-recorded shiur. i am looking for a way to do this as economical as possible. i imagine it would be some sort of voip system or something similar. i need the ability to be able to easily change the recorded shiur. i am thinking that the shiur would be recorded on a mp3 or similar concept then be uploaded. is this possible? would anyone be able to direct me? i have no idea as to where to start, all i have is the concept.
thank you!
