Hi..I have questions about WarVox..

Firstly can I dial a range of any worldwide International numbers like country codes +44, +555 or is it only limited to +1 only.
2. Can the digits be more than 10? like 11 or 12 digits.. Can this also apply to the caller ID number range.
3. Will I be charged by my VOIP providers for 2-3 second rings? or just on connect.

If WarVox cannot do the above..What Autodialer can?
P.S..I am not interested in looking for PBX's or SIP's only the 2-3 second miss call feature..Thank you.
