It got a bit more complex because the code in Asterisk expected a fixed key length of \
30 bytes. Furthermore on egress, Asterisk offered just a single crypto suite, which \
would have made it incompatible with legacy implementations. Anyway, there you go: \
<https://issues.asterisk.org/jira/browse/ASTERISK-26190>


If you need a backport to Asterisk 11, just ask. However, please, motivate why you \
cannot update to Asterisk 13, yet.
