Make call programmatically using PJSIP 2.5 in iOS

Question

After integration of PJSIP, to make a call from my application I am using this code:

sip_dial(voipManager._sip_acc_id, [dialedUser UTF8String], &id_call);

But it returns a 420006 status code while tracing, which shows:

Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006]

I have enabled codecs from manager file, and it's showing "enabled" while compiling also. Where is the point I am missing or misleading?
