UC520(config-telephony)# service phone ehookEnable 1
U520(config-telephony)# create cnf-files
If auto asnwer is required or desired, the following command under the ephone configuration needs to be added (and the IP phone reset)

In general, the vendors are using the phones aux/rs-232-like port as the interface to the phone. A adapter/HHC cable goes between the wireless base station and the headset port on the phone.
The Headset Hookswitch Control (HHC) feature is now fully available via Cisco phone firmware and hardware from GN Netcom.
Highlights:
• Functionality: desktop phone user on wireless heaset can receive ring indication remotely, plus go onhook/offhook and control volume/mute, all without the burden of a mechanical lifter. This type of HHC functionality is also commonly referred to by the term ‘Electronic Hookswitch’
• Requires wireless headset, base station and HHC adapter cable. Jabra GN9350 and GN9120 model headsets have been tested and certified compatible via the Cisco Technology Development Partner program (reference: http://www.cisco.com/pcgi-bin/ctdp/displayProfile.pl?PARTNER_ID=62788). ; Technology is DECT: can answer/end calls up to 300 feet away from desk
• Available only on Cisco Unified IP Phones 7942G, 7945G, 7962G, 7965G and 7975G
• Enabled via 8.3(3) firmware (available since Oct ’07);
This feature bolsters Cisco’s UC story, allowing users to benefit from enhanced mobility and the ability to multitask (including leaving the desk area) while on a call. The wireless freedom improves ergonomics and work efficiency throughout the day. Note that it’s also a differentiator for the new ‘Advanced Media’ 79x2G and 79x5G model phones.
