[Asterisk-Users] Is Asterisk for me?

[Zach Mesel]

Hi there.

My wife and I run a small business out of our home.  We have 2 phone
lines, and don't currently need any additional extensions.  What I and
am in great need of is a voicemail system with the following
functionality:

- When we don't pick up one of our regular phones, the system
  should play a greeting for callers, then allow them to either:
  - leave a message without selecting an mailbox number (or by
    pressing #)
  - select an extension (really just a mailbox, since I don't think
    we'd use any extension phones), whereupon:
    - the user may press 1 to locate the mailbox owner, whereupon 
      the system then dials out to a cell phone using the 3-way 
      calling feature of the telco line.
    - the user may press 2 or stay on the line to leave a message

I have read the * doc and faqs, and I think I can accomplish all of this
functionality using 2 Wildcard X100P cards w/ * on my P4 2.4GHz box with
RedHat 8.0.

Of my desired functionality, is there anything that * won't be able to
deliver?  Is there anything which will be extremely complex to setup,
given that I am (or would like to think I am) a competent Linux SysAdmin
and fair-to-midland programmer?

Thanks in advance for helping me with this decision.
