It'd be nice to be able to see the caller ID of the person leaving a voicemail in case he/she forgets to leave the number in the voicemail. In a call center environment where people can leave voicemail, it is really imperative to be able to track the caller ID of the voicemail. Sometimes people forget to leave their number or the voicemail can at times be unintelligible. With high volume of voicemail, this can happen quite a lot of times a day. Hope this is something that added in the coming service packs.
