Details
codeclicence is an AVM internal tool to set or get the hidden licence keys for nonfree VoIP Codecs like G.729.
It was never part of any release firmware or Labor, but it leaked in exactly 2 english (likely ISP dedicated) Labor files.
The keys are stored in the hidden TFFS-Configuration files codec0 and codec1, without any defaults in ADAM2 / EVA.
A Recovery.exe preserves these keys while cleaning and recreating the TFFS, see the get-codecs feature.
The keys use AES128 encryption, provided by libavmcipher.so. Programs which access them use the low-level libtffs.so.
libtffs.so is used by codeclicence, dect_manager, run_clock, telefon and voipd. But only codeclicence and voipd use
libavmcipher.so and contain the AES128 passphrases, so the keys are only for voipd, as expected.
Fw 4.07 help:

tffs_open tffs_read_value tffs_write_value tffs_close AES128_Environ CIPHER_Init CIPHER_Update CIPHER_Cleanup
