Seems it was done years ago [1] using CSD (data) channel:
"Secure Voice is protecting you against GSM voice interception. Your
mobile operator is not capable to record your conversation when you are
using Secure Voice. Industry usual GSM interception hard- and software
is not able to catch your conversation. Additionally to this: You
personally can choose the desired security grade.
There are two versions of Secure Voice: Secure Voice CSD and Secure
Voice 3G. They differ in the way the encrypted data is transferred from
one mobile to another."
Cost of CSD connection seems to be like for sending a fax.
