Stop call recording in middle of call

Hi Guys,
I have a requirement to stop a call recording in Elastix 2.5 / 2.4 while the extension is put on "Always"
This is because by default we need to put in on always to record all calls but to pass some confidential information over the ph we can dial #1 / *1 to stop the recoding.

Any suggestions
