I have an old Linksys 2102 set-up and connected to voiptalk its Software Version: 3.3.6. I have had look out on the web and seen there is a new version of the firmware 5.2.12 from the CISCO site.
Should we be upgrading to this newer version? or is the default 3.3.6 that was shipped with it best to stick with.
However... The firmware you mention above has been out some time now and it's stable, you can safely go ahead and update it.
