voicemails that are succinct and informative

[sunsunmoon]

Return calls in a timely fashion; failure to do so reflects poor customer service. Voicemail can be both friend and foe. As a caller, be sure to leave voicemails that are succinct and informative. Leave your name, business, reason for your call and contact information.

Would it be incorrect to say "succinct and informative voicemails" in place of voicemails that are succinct and informative?
