Hello,

We have a phone app that ties back to our freeswitch servers. Recently the android phones are getting one-way audio. It works on iPhones and desktop clients. Based on the pcap's and fs_cli I see that the audio ports changed after the sdp negotiations. Not sure why this is happening also see that the codec is set to "BUG Codec PCMU:0"

Any Suggestions?
