Many people feel that VoIP will really only “take off” when it can really emulate all the functions which users are used to in the PSTN:

Integration with the web via: Click-to-connect
“Dialing” an e-mail address or URL {digits vs. strings}
Intelligent network (IN) services:
- Call forward, busy
- Call forward, no answer
- Call forward, unconditionally
- Call hold
- Call park
- Call pick-up
- Call waiting

- Consultation hold
- Do not disturb
- Find-me
- Incoming call screen/Outgoing call screen
- Secondary number in/Secondary number out
- Three-way conference
- Unattended transfer
