Extention Security

Hi All,

If you have a lot of remote extentions that connect through the internet to your TRIXBOX, how can you implement security in this case.

Is there a way to implement AAA to ATA's and IP Phones that connect directly to the TRIXBOX through the internet?

Is there a way to authenticate an extention via its MAC address? There has to be a more sure way to futher authenticate the end user other than a regular extention name and secret ?

any ideas?
