I noticed something odd:

Jingle:Conn[0x1578a3200:audio:N8NQho4A:1:0:local:udp:[fda5:9b29:5b4d::3da4:bb37:bdd5:1a22]:60425->N8NQho4A:1:2122265343:local:udp:[fda5:9b29:5b4d::3da4:bb37:bdd5:1a22]:60425|CRWI|0|0|9115060245863753214|2]

The same address appears as the local and remote candidate. So I'd guess that candidates are getting mixed up, and the iOS client ends up trying to connect to itself, hence role conflicts (it can't be both roles at once). Are you sure you're only calling "addIceCandidate" with candidates from the remote endpoint?

yes you are right, I added the candidates back to the peer connection on ice_candidate callback, this caused the error

I removed this , now it's working

Thanks much for your reply
