Hands down for pretexting is SpoofCard app. You have to buy credits, but it is so worth it. You can record the calls made to send to your clients. You can change your voice to a male or a female. You can choose background noise. I use the lost dog pretext a lot so use the dogs barking noise choice. You can insert any number for the caller ID so if I pretext a flower delivery I goggle an area floral shop and use that phone number. https://www.spoofcard.com
