No audio with chan_motif

hello, i’m trying to get work chan_motif and GTalk. The login works perfect, but when motif calls to a gtalk user or a gtalk user trys call motif, there are not audio in any channel. I have nat 5222 and 10.000-10.225 (rtp.conf) in my router to my Asterisk.
Asterisk 11.1.2
Debian GNU/Linux wheezy/sid

motif.conf:
[default]
[google]
context=incoming-gtalk
disallow=all
allow=ulaw
connection=google

xmpp.conf:
[google]
type=client
serverhost=talk.google.com
username=my_user@gmail.com
secret=my_pass
priority=1
port=5222
usetls=yes
usesasl=yes
status=available
statusmessage="Hello from Asterisk"
timeout=5

rtp.conf:
[general]
rtpstart=10000
rtpend=10255
icesupport=yes

my_user@gmail.com, then i do in cli:
originate Motif/google/other_user@gmail.com application playback /home/pi/mp3/monkey

and i see the call is answered and the file played, with no vissible errors. I try to call, and the same result. Where is the error? What may i do to fix it?

i’ve try many times and if i answer in Chrome in Windows 7, have audio. But if i answer in gtalk app in Android, no. I really need answer in Android, please help.
