sounds like a bug to me. Try master?

Hello,
I apologize for my bad English.
Three years ago there was a message http://lists.freeswitch.org/pipermail/freeswitch-users/2015-June/113829.html <http://lists.freeswitch.org/pipermail/freeswitch-users/2015-June/113829.html> and here I am faced with the same problem. A stupid provider sends crypto in RTP/AVP and to ensure processing this request, I inserted in the profile the parameter NDLB-allow-crypto-in-avp=true But Freeswitch answers to INVITE inserting in OK this line: m=audio 0 RTP/AVP 19 and the provider understands this as "no audio" and does not send ACK and does not send rtp.
How to deal with this I do not know.
