Our engineers have specially designed our phones and software which allow you to record your greeting before your big day or special event. You can record this as many times as you like and even if you want to change this last minute you can. Everything is completely self contained within the phone. You do need to send us the recorded greeting as you will can this yourself in your own time! All the instructions are within the box we send out to you and if you have any problems you can call us or pop us an email and we will get back to you within a few hours.
