Hi everybody
I have an asterisk(172.16.1.33) and freeswitch(172.16.1.30) 
My scenario :
  1. Calls come to freeswitch ivr menu
  2. In ivr calls transfer to asterisk after running an python script freeswitch start recording voice
  3. In asterisk calls push to an queue
my python script is :

############################################################
import paramiko

hostname = '172.16.1.33'
port = 3022
username = 'root'
pkey_file = '/root/.ssh/id_rsa'

def get_agent_id(num):
    command="asterisk -rx \"pjsip show channels\" | grep -a1 \"CLCID: \\\"%s\\\"\" | grep Channel | cut -d \/ -f2 | cut -d\- -f1 " % (num)
    key = paramiko.RSAKey.from_private_key_file(pkey_file)
    s = paramiko.SSHClient()
    s.load_system_host_keys()
    s.connect(hostname, port, pkey=key)
    stdin, stdout, stderr = s.exec_command(command)
    result=str(stdout.read())
    s.close()
    return result

#if __name__ == "__main__":
#    agent_id=get_agent_id('1000')
#    print (agent_id)
import freeswitch as freeswitch
def handler(session, args):
    caller_num = session.getVariable("caller")
    agent_num = get_agent_id(caller_num)
    session.setVariable("AGENT_NUM", agent_num);
    session.setVariable("CALLER_NUM", caller_num);
