I am trying to figure out why an ASA is required for a CUMA deployment, if the only CUMC clients are going to be
The ASA acts as a proxy for all communication.
But in the case of a Blackberry deployment, the BES server does exactly the same thing.
However, looking at the docs, it looks like the CUMC on the Blackberry does not communicate via BES/MDS,
but rather the mobile carriers GPRS / data network, thus requiring the ASA....
It seems strange, why the client on the Blackberry cannot just use the BES/MDS/IPPP data channel, and elimanate the
need for an ASA.
Any comments ?
