27. Hi, It’s [your name] of [your company]. I’m in a meeting at the moment. Please leave your message and contact information, and I will get back to you within [realistic timeframe]. Thank you for calling.
Although this system is showing its age, Visual Voicemail is built-in on the larger display Synapse phone (pictured above), allowing you to navigate and manage voicemails as you scroll through your e-mail on your smartphone. Reliability and build quality are absolutely exceptional. It also offers the ability to connect multiple locations together for calling from store-to-store, for example. The included warranty is 2 years with an option to extend to 5 years. You cannot go wrong with this versatile AT&T solution! Unfortunately, it doesn’t support upgrading later to VoIP and the system does not offer a mobile app and the system was discontinued last year.

That’s the risk you take when you use an ineffective communication channel. But texting gives you one less thing to worry about.
You might also consider giving them the option to skip your voicemail message completely by pressing another key (again, check with IT). You also want to make callers aware what you will return their call, instead of telling them that you will try to return their call--and let them know when you are likely to do it, if possible. If necessary, provide additional or emergency information in your voicemail greetings. My dentist, for example, lists his cell phone number for emergencies.
