您如何在经过星号转换的星号上转移呼叫

Question

我在kamailio服务器后面有一个星号服务器。我希望打个电话，立即转接到手机号码。这是我的拨号计划：

from tkinter import *
import random

root = Tk()

guess = 5

easy_words =      ['hard','boat','tree','free','easy','home','wife']

medium_words = ['medium','mirror','window','floors','trails','pumped','excite']

hard_words = ['envelope','develope','dispatch']

word = ''
wordlist = []

gallows = Label(root)
gallows.place(relx = .01, rely = .2,    relheight = .33, relwidth = .98)

def get_word(diff):
      global easy_words,  medium_words, hard_words, word,wordlist
       if diff == 0:
               word = random.choice(easy_words)
       elif diff == 1:
               word = random.choice(medium_words)
       elif diff == 2:
               word = random.choice(hard_words)
       else:
               pass
       wordlist = list(word)
             for let in wordlist:
                     let = Label(gallows, text = let)
                     let.pack(side = LEFT)



 easy = Button(root, text= 'Easy',command = get_word(0))
 easy.place(relx = .01, rely = .01, relheight = .05, relwidth = .32)

 medium = Button(root, text= 'Medium', command = get_word(1))
 medium.place(relx = .34, rely = .01, relheight = .05, relwidth = .32)

 hard = Button(root, text= 'Hard', command = get_word(2))
 hard.place(relx = .67, rely = .01, relheight = .05, relwidth = .32)


 root.mainloop()

100％的时间会呼叫该号码，但是有时没有音频。我该如何解决这个问题？
