[Asterisk-Users] Question regarding SER/Asterisk functionality

["Geir O. Høgberg"]

Hi all,

I'm currently looking for a VoIP platform to support the following features:

Caller ID
Call Waiting with caller ID
Call Hold/Retrieve
Three-way conference
Calling Line Identity Presentation
Call back last missed call
Last called number redial
User line locking/Call Barring (all current levels)
Itemised bill
Call Forward
Call Forward on No Reply
Call Forward on Busy
Call Forward Unconditional
VoiceMail
- Message Waiting Indicator
- Call back option
Number Portability
Secret Number
Legal intercept
Emergency Number Routing
Anonymous Caller Rejection
Directory Service update
Feature code activation

I have looked into both SER and Asterisk, and found out that SER should 
be the most appropriate platform since most of the users will use a SIP 
adapter/endpoint and be located on the Internet (like most of the VoIP 
services these days).
So my question to the list is to gather some experiences and possible 
remarks/comments on which direction I should go :D

Any help would be gladly appreciated :-)
