Asterisk trixbox conference server with fax, sms & voicemail

I have a Asterisk Trixbox on a box installed on public IP. I need some quick and easy stuff done to use it as a conference server: Scenario: people will call in a SIP inbound number configured on the server. They can participate in a conference, they can send receive fax, they can send receive SMS and they can listen to voicemails left for them. So, we need following: - Conferencing: standard conferencing including Auto attendant for conference participation...Conferencing can happen between SIP IP phone, SIP softphone, and PSTN users. - FAX: send email as FAX and receive FAX as email - SMS: Send/ receive SMS - Voicemail: People could leave voicemails, and users can listen to their voicemails. This should be only few hours job for anybody who knows what he/she is doing. This is an urgent project. I will need to be demoed the completely working system. Also, at least one week support will be required while we test the system. Let me know if you have any queries.
