Summary:                    "rtptimeout" doesn't terminate channel if RTP is
lost during "Echo()"
Description: 
I set rtptimeout=20 in sip.conf and call from a softphone to extension
501:

  exten => 501,1,Answer
  exten => 501,n,Echo

During the call I kill the softphone (RTP ended and SIP BYE never received
by Asterisk).

After a while (qualify=yes) softphone peer appears as UNREACHABLE.
Asterisk gets "ICMP host UNREACHABLE" when sending RTP to client.
And 20 seconds after (rtptimeout) nothing occurs, the channel remains open
and will never be hangup. Why?

I forgot to say that softphone is behind NAT with:

[user]
type=friend
host=dynamic
qualify=yes
nat=yes
dtmfmode=info
canreinvite=yes
