Since Vonage didn't want to add this feature in their web dashboard, i made a PC applicaiton that sends you an email/sms whenever you miss a call. Quite handy if you are on the go. To get a free eval version email me at nikola.bulatovic@gmail.com or call (408)393-5848

I would most definitely like the CLI assignments. We have 3 Vonage numbers we use for business and we would really like all our outgoing calls to appear like they're coming from one number. I'd also really like them to release the SIP settings so we can use a Softphone on the same numbers too.
