So you've confirmed that a later release of Asterisk solves the problem
you are trying to resolve, but your customer won't let you use that
version. What do you expect people here to be able to do to assist you?
Either you upgrade to the version that has the problem resolved, or you
figure out how to backport the relevant changes into the version you are
running... but that seems to also violate your customer's restriction
that you can't change Asterisk versions.
