i got a reply from zoiper devs and they r blaming it on FS "We have done some test with Freeswitch version 1.4.26 and there are no problems with Opus. Most probably something has been changed in the newer versions of Freeswitch."

is there any1 using opus codec with FS using zoiper on android, coz im banging my head from past few days but calling from zoiper to zoiper always gives one way audio even though the other way RTP reaches FS but it doesnt send it back to zoiper and thats the cause of one way audio. I tried playing with the opus settings in almost all combinations but it just doesnt work, my profile has late negotiate and inherit codec enabled, tried disabling inherit codec but its still the same. FS cli also doesnt show any error regarding y it isnt sending the RTP back to dialer even though it gets it from the other zoiper

the packet trace is there on jira FS-9270 if any1 wants to investigate, any help is appreciated
