pyhotn的p2p-sip网络电话小试牛刀

p2p-sip是一个P2P的电话协议，有人写了python实现。

这个只支持python2，2.6以上

pip安装，或者下载安装包解压。

解压后有readme，啃一下英文。

编写webcaller.py

import gevent, sys
from gevent import monkey; monkey.patch_all()
from gevent.pywsgi import WSGIServer
from cgi import parse_qs, escape
import logging
from logging import config
logging.config.fileConfig('logging.conf')
#logger = logging.getLogger(__name__)
logger = logging.getLogger()

from caller import Options
from gevent import queue, Timeout

freeAccounts = queue.Queue()

from app import sipstackcaller

bac, int_ip = None, None
maxwait = 5

import Queue

def application(env, start_response):
  d = parse_qs(env['QUERY_STRING'])
  peers = d.get('peer', ['unknown'])

  response_body = ''
  if env['REMOTE_ADDR'].startswith('14.29.2.') or env['REMOTE_ADDR'] == '127.0.0.1' \
    or env['REMOTE_ADDR'].startswith('192.168.36.') or env['REMOTE_ADDR'].startswith('10.17.41.'):
      gevent.spawn(callpeers, peers)
      status = '200 OK'
  else:
    status = '403 Forbidden'

  response_headers = [
        ('Content-Type', 'text/plain'),
        ('Content-Length', str(len(response_body)))
  ]
  start_response(status, response_headers)

  return [response_body]  

def callpeers(peers):
  user, domain, password = None, None, None
  try:
    for peer in peers:
      peer = escape(peer)
      peer = 'sip:'+peer+'@gd.ctcims.cn'
      logger.info('calling ' + peer)
      (user, domain, password) = freeAccounts.get(timeout=maxwait)
      try:
        options = Options(user, domain, password, bac=bac, int_ip=int_ip, to=peer, uri=peer)
        caller = sipstackcaller.Caller(options)
        gevent.sleep(30)
        logger.info('hangup call to ' + str(caller.options.to))
        try:
          gevent.with_timeout(10, caller.close)
        except Timeout:
          logger.warn('caller.close timeout')
      except Exception as e:
        logger.warn(e)
      finally:
        if user and domain and password:
          logger.info('freeAccounts.put')
          freeAccounts.put((user, domain, password))
  except Queue.Empty:
    logger.warn('get from queue  timeout')
  except Exception as e:
    logger.warn(e)


def hangup(caller, account):
  try:
    caller.close()
  except:
    pass
  finally:
    freeAccounts.put(account)
  logger.info('hangup call to ' + str(caller.options.to))

if __name__ == '__main__':
  try:
    argv = sys.argv
    i, username, password, media, bac = 1, None, None, None, None
    int_ip = '0.0.0.0' 
    jobs, callers = [], []
    while i < len(argv):
      if argv[i] == '-u':
        if username:
          (user, domain) = username.split('@')
          freeAccounts.put((user, domain, password))
          username, password = None, None
        username = argv[i+1]
      elif argv[i] == '-p':
        password = argv[i+1]
      elif argv[i] == '-b':
        bac = argv[i+1]
      elif argv[i] == '-i':
        int_ip = argv[i+1]
      i += 2
    (user, domain) = username.split('@')
    freeAccounts.put((user, domain, password))
  except:
    logger.exception('exception')
    sys.exit(-1)
    
  print('Serving on 8088...')
  WSGIServer(('', 8088), application, log=logger).serve_forever()

首先要定义一个常量：

export PYTHONPATH=.:external:std:app

然后调用webcaller启动：

python webcaller.py -u [email protected] -p password -b ip

服务启动成功会启动8088端口监听

调用http://127.0.0.1:8088/?peer=138xxxxxxxx拨打电话
