I was going by examples from FreeSWITCH 1.2 book (didn’t see a later release on Amazon).
The following wiki states outdated values as well (and happens to be the first link when googling for freeswitch SRTP):

Subject: Re: [Freeswitch-users] SRTP calls fail 'because secure media is administratively disabled'
That change was made between 1.2 and 1.4, its been multiple years now, not recent.

a call between endpoint 1000 and 1001. The call works fine when SRTP is
disabled on the softphones. The problem starts when I enable SRTP on the
softphones. I also enabled SRTP on FreeSWITCH server, by including the
following command in vars.xml:
<X-PRE-PROCESS cmd="set" data="sip_secure_media=true"/>
When I try to place a call between the two endpoints now, I end up with one
side immediately hanging up.
Specifically, the error seems to be:
[WARNING] switch_core_media.c:4035 Declining invite with only SAVP because
secure media is administratively disabled
Followed by:
[NOTICE] sofia.c:7742 Hangup sofia/internal/1001@10.10.10.112:5060

Couldn't find any info on how to resolve this issue online.
Here's the relevant log:
