[Freeswitch-users] dtmf problems when using flowroute

[covici at ccs.covici.com]

hmmm, so after doing a git bisect, I found that the following commit
breaks the dtmf detection using flowroute
commit 56d83d1967a4d3e278de72887587c767a82364ba
Author: Anthony Minessale <anthm at freeswitch.org>

    FS-8321 #resolve [BEHAVIOR CHANGE Add variable
    media_mix_inbound_outbound_codecs to mix inbound and outbound
    codecs]

Now I do have that variable set just  before the bridge
<action application="export" data="media_mix_inbound_outbound_codecs=true"/>

So, am I doing something wrong or what?

Thanks.

Your life is like a penny.  You're going to lose it.  The question is:
How do
you spend it?
