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?

Can you please provide a sip debug of this? I was unable to reproduce it
but I have a suspicion...
