Hi I wanted to connect my asterisk server (13.X.X-v300) to odoo v11.0.1.0.0 using a module called asterisk_click2dial , now in the form, i typed the required info in the main form of the module, then opened the required ports, when I press the test the connection with asterisk server this error appears, " Connection Test Failed! The error message is: banner incorrect; got 'VoIP API/AMI/2.0.0', expected prefix 'Asterisk Call Manager'" and a log in the asterisk server appears "connection attempt from *.*.*.* unable to authenticate.

i traced the issue in the py-asterisk py file called Manager.py

def _authenticate(self):
'Read the server banner and attempt to authenticate.'

banner = self.file.readline().rstrip()
for enc in ('utf-8', 'latin1'):
try:
banner = banner.decode(enc)
except:
pass
if not banner.startswith(self._AST_BANNER_PREFIX):
raise Exception('banner incorrect; got %r, expected prefix %r' %
(banner, self._AST_BANNER_PREFIX))
action = {
'Username': self.username,
'Secret': self.secret
}

if not self.listen_events:
action['Events'] = 'off'

self.log.debug('Authenticating as %r/%r.', self.username, self.secret)
self._write_action('Login', action)

if self._read_packet().Response == 'Error':
raise AuthenticationFailure('authentication failed.')

as you can see the module can't pass this part of the code.

can anyone help me?
