A good voicemail greeting is short and professional, lets people know that you’ll get back to them, and invites callers to continue engaging with a call-to-action. You should also show your personality if you’re in an industry or role that allows that. If your industry is more conservative, however, you’ll want to keep humor and personal touches to a minimum. A greeting Your name Your company A simple explanation for missing the call (e.g. you’re away from the phone or are on holiday) A rough estimate of when you’ll get back to the person An alternative person to reach out to (if you’re out of office) An alternative mode of communication (if you prefer email or text) A call-to-action such as “Leave a message” or “Send me an email at [email protected]”
You have the option in settings for calls to be answered either via the app itself (check off iOS Device) or by having the call forwarded to your mobile number. Either way, you are not technically doing the recording on your iPhone. It's all done on Google's servers, which handle the Voice over IP (VoIP) connection.

IPhone 4S rings once then goes to voicemail? When people try to call me sometimes my phone rings once, then goes to voicemail and sometimes doesn't ring at all. They have to call me at least 2-3 times before it actually works.
But what’s really great about Samsung’s way of dealing with voicemails is the new and improved Visual Voicemail service. This lets you view voice mail messages and listen to them in any order you want. Instead of listening to all of them in order, you can pick the ones you’re interested in. Even more, you can decide to erase or archive them, all from your device screen. Visual Voicemail also includes button shortcuts to call back or text a person that left you a voicemail.
