first i want to thank the developers and contributors of this amazing
we have been using freeswitch for almost 4 years without a major problem.
i have a question regarding inband dtmf.
we have receiving calls from telco using dtmf rfc2833. most of outgoing
dtmf rfc2833. but we have a new outgoing profile which is behind a
firewall. we did
not make a successful call with transport UDP. so we set the transport to
now we have successful calls but the only problem is with dtmf. when we set
the dtmf to
rfc2833 for this profile, we saw that dtmf packets do not arrive correctly
destination. when we dig up the problem we realized that there is always a
on dtmf packets. for this reason we tried to set dtmf inband for this
profile. to accomplish this we used start_dtmf_generate just before the
but this time no dtmf package arrive at destination. is this dtmf
conversion (from rfc2833
to inband) even possible?
what should be the correct configuration to achieve this?
