Summary:                    DTMF package's ssrc number wrong when partical
bridge channel
Description: 
I using asterisk-1.4.20.1 as my pbx,with two extensions(2000,8888),my
asterisk register a sip provide by 8888.The provide can dial into pstn.
sip.conf
[general]
register => 8888:8888 at myprovide
[anthentication]
auth => 8888:8888 at 172.21.9.202
[8888]
username=8888
type=friend
secret=8888
host=172.21.9.202
context=test_context
canreinvite=no

[2000]
type=friend
secret=8888
host=dynamic
context=test_context
canreinvite=no

extension.conf
[test_context]
exten => _9.,1,dial(sip/8888/${EXTEN},,)


when I make a call from 2000 by pressing 910086,the call be setuped and I
can hear IVR,then I press some number key on the phone,but nothing
happend.during the test,I captured package. From the packe I found asterisk
bridge them as partical bridge that I don't know what is meaning.and
asterisk using the wrong ssrc in dtmf package.



if I allow asterisk to reinvite,this won't happen,but it is native
bridge.
If I disallow asterisk to reinvite, but change dial rule as

extension.conf
[test_context]
exten => _9.,1,dial(sip/8888/${EXTEN},,T)

asterisk bridge two channel in generic mode, but asterisk didn't forward
any dtmf package


Sorry for my poor english
