send image via instant message with pjsua2

Hi all:

Is it possible to send images (or other binary files) via pjsip instant
messaging using pjsua2? I am using pjsip 2.7.1.
I can IM text messages fine, but when I try and send a binary file I get
err=171023 (Message too long (PJSIP_EMSGTOOLONG))

I read the FAQ and did quite a bit of searching, so hopefully I'm not
missing anything obvious.

Here is the python method I am using:

def send_file(self, buddy, file_path):
'''sends file via sip IM'''
(mime_type, mime_encoding) = mimetypes.guess_type(file_path)
self._logger.debug('mime_type = %s', mime_type)
self._logger.debug('mime_encoding = %s', mime_encoding)
if mime_type is None:
self._logger.debug('could not determine mime type for file %s',
file_path)
else:
with open(file_path, 'rb') as file_reader:
file_contents_bytes = file_reader.read()
file_reader.close()
self._logger.debug('len(file_contents_bytes) = %s',
file_contents_bytes)
base64_data = codecs.encode(file_contents_bytes, 'base64')
string_data = base64_data.decode('utf-8')
send_im_param = pj.SendInstantMessageParam()
send_im_param.content = string_data
send_im_param.contentType = mime_type
buddy.sendInstantMessage(send_im_param)
self._logger.debug("sent binary instant msg with length %d to
%s", len(file_contents_bytes), str(buddy))
buddy = None
self._logger.debug('buddy set to None')

And here is a snip from the pj sip logs (I can post the entire log if
desired)

Thank you in advance for any help.
