Dear Dr. Jafar

Your voicemail message has been received , thank you for your invitation. However, I’m not sure whether we should prepare a presentation for the conference or not, and if we are invited as visitors. Also, I’m sorry that I don’t get the time and the place exactly.

On the other hand, I hope that we could bring some of our equipment, I think it could be a good contact.

Regards

Dear Jafar

I’ve got your voicemail message, it’s very nice of you, thanks again. Well, but I’m sorry that I don’t understand if I should make a speech during the conference and if I am invited as visitor. And actually I don’t get the right time and place, please tell me.

By the way, can I bring some of our equipment? I think it could be a good contact.

Yours
