An oncologist is a type of doctor who deals with patients afflicted with one or various types of cancer. His/her work involves consultation, diagnosis, application of chemotherapy and coordinating with other doctors involved in treatment etc. This is how the phone greetings for oncologist should be like:
19. Hi, you’ve reached [employee name]’s voicemail box. [Employee first name] no longer works for [company name]. Please call our main line at [phone number] and we’ll be happy to connect you with a current team member who can help.

Please note that if you record an unavailable greeting, it will be used instead of the default message with your name recording.
The above section details types of phrasing to avoid; however, it doesn’t detail what users should NOT say on their greeting. Though this is a bit loaded, as there are hundreds of combinations of things one shouldn’t say, there are some key components users should ALWAYS avoid. a. Forget About Slang: You should strive to be as professional and welcoming as possible in your greeting. While this may steer you towards using slang, in an attempt to make callers comfortable, it’ll most likely work against you. As a professional, your demeanor, tone, and speech should be clear cut and well articulated. Using slang undercuts this and works against you. b. Don’t Even Think About Profanity: This is a no-brainer. Never, under any circumstances, curse in your greeting EVER! c. Keep Your Sentences Clean, Don’t Ramble: Introduce yourself and give your caller specific direction. Avoid long diatribes detailing tangent thoughts. Keep it simple and quick. d. Always Return Your Calls: It’s important for callers to feel they are valued. Nothing dissolves this quicker than a greeting that doesn’t stress this. For example, “I’ll call you when I can,” “If I don’t return your call, please call back”—these phrases are terrible and completely destroy any good will you may have with a caller.
