I get asked quite a lot what the options for outbound fax for Exchange 2007 are and up until now I have had to say 'its available from third party vendors'.

I am pleased to say that I recently discovered one vendor that we have been working with in particular,  Captaris.

I wont go through what it does because there is more than enough info on their website,  it does look pretty impressive though as it supports tracking of inbound/outbound faxes via the Exchange Messaging Tracking Log,  support for current Office and Windows release and even has the option to transport faxes into Sharepoint .... nice !
