We have a appointment system written in ASP.NET with MSSQL database. We are wanting to add voice reminders to our system, so our prerecorded message is played to a client 1 day before their appointment.
Does anyone know any software which can do this? We prefer VOIP, specifically using SIP.
I have a programmer which is doing the main system, but he is unaware of any software packages in which could assist us in completing this step. We do have a dedicated server for the communications system we choose.
Any help would be great! Thank-you.
