[Asterisk-Users] Congestion problem

[Tomislav Parcina]

I use to have this in my extensions.conf

[fxo4]
exten => s,1,Dial(SIP/214,20,tw)
exten => s,2,Answer 
exten => s,3,VoiceMail,u214
exten => s,4,Congestion
exten => s,5,Hangup
exten => s,102,Answer 
exten => s,103,VoiceMail,b214
exten => s,104,Congestion
exten => s,105,Hangup

When somebody calls me on fxo4 port * sents that call to SIP 214 phone. 
The problem is that when call ends and SIP user hangs up, the line stays 
up. Now I don't use "Congestion" any more. Can sombody tell me do I 
realy need that congestion signal? On 
http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+Congestion
they say that congestion waits that other party hangs up. Why would I 
wait for that?

Please, any informations are welcome.
