Exchange + "direct push" email

It looks like if we can get our Exchange Server 2003 (SP2)
configured to support Direct Push - that we can support ALL our phones
directly
without the need for additional re-directors....

The mobile phone basically acts as a thin web client and opens a connection
to Exchange
and does not close it - Exchange talks back to the phone across this link.
If it times out - it just gets re-opened...

SO - anyone have a feel for how much data time & money is used
to keep this heartbeat connection open and support "direct push" delivery ?

Guess I'm doing some catch up -

looks like it's built into Exchange 2003 SP2 -

always learning.....

Depends on the amount of email and accounts. Device battery life is more of
a concern than data, since the providers offer unlimited data plans.
Anything less than unlimited will be very costly for the phone plan.

Take whatever you estimate and multiply by two. Depends on your
Server(s), and how many users, and how many messages, and your policy
limits on attachment size. You do I hope
have dedicated Exchange Server(s)?

As with any Server Support issue: You just have to know what you're
doing. Trial and error, learn as you go, is a recipe for disaster.

Always add functionality at 2 AM on a Saturday night.

Of course Yahoo will run its own Push Email for the new iPhones.
