if you use bypass_media=true from the dialplan without late-negotiation set
in the profile, it still tries to match the codecs locally on the inbound
leg and the variable does not work if the call has established media before
making the outbound leg.

It's hard to tell you the exact answer without a console trace on debug
level.
