As of the latest software release by Aastra (2.5.1.2000 Patch July 09), the following Aastra IP Phones now support Electronic Hookswitch (EHS) or otherwise known as DHSG.
If you are not familiar with EHS, it is a feature that allows you to answer your phone using your wireless VoIP headset without the need for a Handset Lifter or corded solution.
You can download and upgrade your Aastra phones with the latest software located here. (Keep in mind these files are model specific so make sure you download the correct file per your phone.)
Now before you go nuts, there are four requirements that must be met for EHS/DHSG to work properly on your Aastra desktop VoIP phones.
If you have met all (4) requirements, you are ready to enjoy EHS/DHSG on your Aastra Phone. If you need anything to fill the requirements above, do not hesitate to call VoIPSupply at 1-800-398-8647 and one of our experienced VoIP Sales representatives will be glad to assist.
