How to Speed up Cingular Voicemail - WikiHow
I logged onto my VZW voicemail, and was able to change my prompting level to rapid prompting as well… Here’s how:

• press 4 for Personal Options
• press 2 for Administrative Options
• press 1 for General Options
• press 8 for Prompt Level
• press 2 for Rapid Prompt

BUT, I have always been able to delete a message by pressing “7″ in the middle of it… so Rapid Prompting only reduces the verbose level of their prompts.
