[python] send_request not working when headers are None or empty

[saghul@xxxxxxxxx (Saúl Ibarra)]

Hi!

While trying to send DTMF tones as SIP INFO requests I found that
send_request does not work properly when headers are None:

This doen't wok:

body = "Signal=%s\r\nDuration=100\r\n" % digit
call.send_request("INFO", None, "application/dtmf-relay", body)

But this does the job:

body = "Signal=%s\r\nDuration=100\r\n" % digit
call.send_request("INFO", ("X-Foo=bar"), "application/dtmf-relay", body)

By reading the pjsua.py code I found this code:

        if hdr_list and body:
            msg_data = _pjsua.Msg_Data()
            if hdr_list:
                msg_data.hdr_list = hdr_list
            if content_type:
                msg_data.content_type = content_type
            if body:
                msg_data.msg_body = body
        else:
            msg_data = None

And obviously msg_data will be None if headers are None :)
