title: Linphone SDK 5 IOS
body: <p>Hello every one im using  Linphone IOS SDK 5 to build app for sip calls
  everything is fine
  now i want do feature to record calls
  i created path for records</p>
  <pre><code>func outgoingCall(to number: String, name: String?) {
          phone = number
          self.name = name
          do {
              // As for everything we need to get the SIP URI of the remote and convert it to an Address
              // We also need a CallParams object
              // Create call params expects a Call object for incoming calls, but for outgoing we must use null safely
              let params = try mCore.createCallParams(call: nil)
              // We can now configure it
              // Here we ask for no encryption but we could ask for ZRTP/SRTP/DTLS
              params.mediaEncryption = MediaEncryption.None
              
              params.recordFile = getWhistleURL().absoluteString
              // If we wanted to start the call with video directly
              //params.videoEnabled = true
              // Finally we start the call
              mCall = mCore.inviteWithParams(url: number, params: params)
              // Call process can be followed in onCallStateChanged callback from core listener
          } catch { NSLog(error.localizedDescription) }
          
      }
