I cant send dtmf via IOS Swift webrtc

[Bilal Şimşek]

Hi all,

I am developing mobile app that uses janus gateway, I coded both ios and android identical, on android dtmf works fine but on ios its not successful to send dtmf but there is no error. 

is there anyway that I can check if dtmf reached to janus gateway. 

in the link code shows preparing peerconnection  and sending dtmf functions.

I also tried add track to directly peerconnection instead of stream but no success. 

any idea will be appriciated.

adding operation to queue solved my problem.

func insertDTMF(_ tone:String){

      

        

        var audioSender: RTCRtpSender?

        for rtpSender in peerConnection.senders {

          if rtpSender.track?.kind == "audio" {

            audioSender = rtpSender

          }

        }

        

        if let audioSender = audioSender {

           let queue = OperationQueue()

           queue.addOperation({

             audioSender.dtmfSender?.insertDtmf(tone, duration: TimeInterval(0.2),interToneGap: TimeInterval(0.5))

           })

        }

    }
