How do I connect my Jabra Engage with my Aastra 53i, 55i, 57i, 6753i, 6755i, 6757i desk phone so I have remote call control using my headset?

• Jabra Link 14201-10 Electronic Hook Switch (EHS) cable
• DHSG connection cable from Aastra
• Aastra 53i / 55i / 57i / 57iCT / 6753i / 6755i / 6757i / 6757iCT phone with firmware version 2.5.1.2000 or later

Connect your headset

1. Plug the RJ10 connector (green) from the split end of the Aastra DHSG cable into the headset socket/port on the desk phone.
2. Plug the RJ45 connector (yellow) from the split end of the Aastra DHSG cable into the socket/port for the expansion module on the desk phone.




3. Plug the single end of the Aastra DHSG cable (blue) in the Aastra RJ45 adapter.
4. Plug the single end of the Jabra Link 14201-10 cable (blue) into the free socket on the Aastra RJ45 adapter.




5. Connect the 2-sided end of the Jabra Link 14201-10 cable to the Jabra base as follows:
   
   1. Plug the RJ10 (small) connector into the socket/port with the phone icon
   2. Plug the RJ45 (wide) connector into the socket marked AUX.

• For Jabra Engage 75/75 SE, follow the onscreen setup wizard on the base.
• For Jabra Engage 45 SE/65/65 SE, the initial setup is complete after connecting the cables.

• EHS cable/adapter type: DHSG.
• Clear dial tone switch: set to position “A”.
• We recommend setting the microphone volume to "7" out of 13.

1. For Aastra desk phone with firmware version 2.5.1.2000, the DHSG mode is deactivated by default. Activate it by using Aastra.cfg or mac.cfg with the command “dhsg:1”.
2. Make sure to set the Audio mode to “Headset/Speaker". Access the phone settings by navigating to Options > Default settings > Audio settings > Audio mode > Headset/Speaker.

Note
There is no possibility for remote call control if you are using an expansion keypad.
