Voicemail greetings are way too long

We all have cellphones these days, and all of them have voicemails. Voicemail systems typically have two greetings - one you record, and the instructional one provided by the system. It's the latter that is in most cases way longer than it needs to be - it lists every possible option every time, which is especially frustrating when you just need to leave a quick note and have just waited for 10 rings for the voicemail to kick in.
