---------------------------------------

    Description: 
Hi all,

After upgrading to the last version of Asterisk (1.8.32.3) when I call a number to CCM (from Asterisk) Asterisk don't manage the:
"Everyone is busy/congested at this time.....Auto fallthrough, channel 'SIP/callman01-00000400' status is 'CONGESTION'" if the CCM close with a busy after some rings.

Upgrading to the new and last branch (13.x) I've the same result.

Downgrading to Asterisk 1.8.29.0 (my old version) it works correctly!

Here is the verbose log:

a) v. 1.8.29.0 
{noformat}
....
Scheduling destruction of SIP dialog '6a49af6955b2084b7b37465a5992be6e at xxx.xxx.xxx.xxx:5060' in 6400 ms (Method: INVITE)
  == Everyone is busy/congested at this time (2:0/1/1)
-- Auto fallthrough, channel 'SIP/callman01-00000400' status is 'CONGESTION'
{noformat}
...In this case the user hear a vocal message that is related to the busy/congestion signal.

b) v. 1.8.32.3
{noformat}
...
Scheduling destruction of SIP dialog '6e7686d8178cd38a56d8a69a14bab358 at xxx.xxx.xxx.xxx:5060' in 6400 ms (Method: INVITE)
{noformat}
...In this case the Asterisk user hear ringing forever even if at the other side the CCM has returned to Asterisk the Busy/Congested signal
...Also the line from "sip show channels" after the "CCM close" disappear, but not the ringing/call.

Is a new bug or it has already been solved?

If not, could anyone patch it?

Thanks in advance

PS: Here a sample config:
