Hi
Even a simple 3 line code is giving same error. Can anyone help on this?
import pjsua2 as pj
recorder=pj.AudioMediaRecorder()
recorder.createRecorder('file.wav');
return _pjsua2.AudioMediaRecorder_createRecorder(self, file_name, enc_type, max_size, options)
NotImplementedError: Wrong number or type of arguments for overloaded function 'AudioMediaRecorder_createRecorder'.
Possible C/C++ prototypes are:
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &)
I tried trunk,2.8 and 2.7 and same error.

Hi all
Able to resolve 1st issue, by shifting call.answer to main thread. Struck with second issue, i.e how to create recorder to record to a wave file. Any help is welcome.
recorder=pj.AudioMediaRecorder()
recorder.createRecorder('xxxxxxxxxxx/PJSUA2/example/pygui/file.wav');
gives following error
-----------------------------------------------
Traceback (most recent call last):
File "pjsua2_cli_demo.py", line 33, in onCallState
self.recorder.createRecorder('xxxxxxxxxxxxxx/PJSUA2/example/pygui/file.wav');
File "xxxxxxxxxxxxxxxx/.local/lib/python3.6/site-packages/pjsua2.py", line 4110, in createRecorder
return _pjsua2.AudioMediaRecorder_createRecorder(self, file_name, enc_type, max_size, options)
NotImplementedError: Wrong number or type of arguments for overloaded function 'AudioMediaRecorder_createRecorder'.
Possible C/C++ prototypes are:
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &)
------------------------------------------------
Thanks.

1. In each call back function, at the end I need to add a dummy raise exception, else it misbehaves. For example, if I comment dummy exception of onIncomingCall, incoming call will get disconnected with 500 error. In pyGUI, it looks like ttk.master.after()
plays critical role. As I am trying it in a headless server (mean only cli), not sure how to handle it?
2. When I try to use createRecorder getting following error
