Asterisk dialplan - waitexten hangs up immediately and does not wait

Question

Consider the following asterisk dialplan. After the last sound file is played it hangs up immediately and the waitexten timeout parameter seems to be ignored. The behaviour I am trying to achieve is to wait a given number of seconds after the last sound file is completed to get a response and then hang up. The last sound file says "Dial * to hear these options again". If I set the waitexten timeout to say 60, it hangs up before the sound files are played. A shorter time allows them all to be played but then it hangs up immediately. Any suggestions for handling this a better way are welcome

[mainmenu]
exten => s,1,Wait(0.25)
  same => 2,Answer()
  same => 3,Background(/srv/asterisk/sounds/optionslist)
  same => n,Background(/srv/asterisk/sounds/dial2cs)
  same => n,Background(/srv/asterisk/sounds/dial3ma)
  same => n,Background(/srv/asterisk/sounds/dial4ac)
  same => n,Background(/srv/asterisk/sounds/dial0)
  same => n,Background(/srv/asterisk/sounds/dialstar)
  same => n,WaitExten(20)
exten => 2,1,Goto(cs,2,1)
exten => *,1,Goto(s,3)

I assume that you have a problem like in this topic Asterisk,SIP Retransmission timeout. Try to solve the problem with the NAT settings or firewall.

In this answer propose to set canreinvite=no in sip.conf.
