Appendix A: Remote Operation Key Codes
– Quick Reference
During a call, the following operations can be performed on the phone by dialing a key code sequence from
the remote side phone which supports the sending of DTMF
21
. If configured, these operations may require
DTMF authentication codes (Refer to 4.8 Authentication: DTMF Authentication Code).
Here is an example of how to use the DTMF operation codes during an active call.
For example, to adjust the volume of speaker from a remote phone, follow these steps:
Authenticate using key sequence *4**. Successful authentication is indicated by a
single beep. This step is required only when DTMF authentication is enabled for volume adjustments (Refer
to 4.8 Authentication: enable/disable the DTMF authentication)
Dial the key sequence *31*8*. This sets the volume level of the speaker to 8. Successful operation is
indicated by a single beep.
Note The DTMF Authentication Code is only required once during a call and is valid until the call is
terminated.
