Hi,

No, it's not even connecting.
On the caller side, I do not see anything showing that the called
party picks up.

On the D70 side, when I pick up, I have the counter starting so I can
see the seconds going up, but no audio at all. (and the remote party
still hears ring tone)

I added port 5061 without success.
I am wondering if I used a man in the middle like iptel.org service,
it would work  ?

Each asterisk call uses 3 ports;  5060 is used to initiate the
connection
(5222 for chan_motif/google voice), then 2 consecutive ports from
the
10001-20000 range are used for voice.  Since GV uses TLS, I'm
wondering if
5061 also comes into play.  I assume you started from this link:

Danny,

I tried netstat -anp on a working outgoing call, and non working
incomgin, and I see that the working has "CONNECTED" status, while
the other one has nothing like that at all. Any other idea ?

Thanks

Do a "netstat -anp" during the call.  This will (hopefully) show
you where the out of range condition is occurring.

Danny,

Thanks for the trick, that made all outgoing calls working.
Now, the issue is with incoming calls. Even if I turn off all other
phones in google voice configuration and have the calls routed to
my Google Chat only, this is what happens:

The Asterisk receives the call.
The D70 rings.
If I pick up, nothing happens (I see on the D70 display that I
picked
up) The caller still hear the ringing tone

THat's what I see on the console:

*CLI>     -- Executing [[email protected]@gtalk_incoming:1]

You are obviously getting the call connected, so the subnet issue

moot.

What this sounds like (pardon the pun) to me is an rtp skip issue.
The "working" calls are generating rtp connections in the allowed
range; the other calls have one or more ports outside of your rtp
range.  Verify that all of your ports defined in rtp.conf
(10000-20000 by default) are open in the firewall.

Chris,

I covered the whole 74.125.225.* subnet.
Even if I open the ports mentioned below for all (not limited to
IP
addresses) I still have the same issue.

Have anyone ever succeeded in such configuration? :

Digium phones on 2 different private networks (2 different
buildings) Asterisk server in the internet with a public IP Use
Google Voice

Even if you have asterisk on a private network, but have the same
kind of solution working for you, I'd love to hear your story..

This may be due to the fact that voice.google.com
<http://voice.google.com> actually resolves to a range of IP

addresses.

When you set up your firewall, it may not be including all of the
possible resolutions for voice.google.com...

voice.l.google.com

(ie 74.125.225.32-41 and 74.125.225.46)

Since these are short TTL values (the 300 means 5 minutes) there
may be a brief period where your devices and your firewall agree,
before one or both change their mind about the IP address behind
that

hostname.




          I just tried out of the blue calling from D70 through
Google

Voice

          to a cell phone, and it worked. I hung up, redial, and
no audio at

all.

              Greetings all,

              I was reading the documentation tonight, and decided
to

try

              Google voice
              with my asterisk.

              I was able to setup iksemel, connect to google using
jabber,

and

              connect
              to google voice using gtalk.


              Here is my physical configuration:

              Digium D70 <-- private network 192.168.1.x -->
Airport express

<-->

              Internet <--> Asterisk with public IP

              My asterisk has the following ports open:
              5060 tcp/udp from my Airport Express public IP and from
              voice.google.com <http://voice.google.com>
              10,000:20,000 from my Airport Express public IP and from
              voice.google.com <http://voice.google.com>

              My issue is that when I place a call with google
voice, I

have

              no audio
              path at all in both way.

              When a call is received on google voice (and sent to
the

D70),

              if I pick
              up, nothing happen, and the caller still hear the
ringing

tone.




              My D70 is setup as follow in the sip.conf:
              [D70]
              type=friend
              nat=yes
              qualify=yes
              directmedia=no
              host=dynamic
              secret=takapoum
              disallow=all
              allow=ulaw
              context=LocalSets
              mailbox=D70@default


              my gtalk.conf is setup as follow:
              [general]
              bindaddr=0.0.0.0
              allowguest=yes

              [guest]
              disallow=all
              allow=ulaw
              context=gtalk_incoming
              connection=asterisk



              and finally, the interesting parts in my
extensions.conf

are

              setup as
              follow:
              ;Dialing out on google voice:
              exten =>

_1zxxzxxxxxx,1,Dial(Gtalk/__asterisk/+${EXTEN}@voice.__google.com

<mailto:[email protected]>)

                    same => n,Hangup()

              ;Google voice incoming
              [gtalk_incoming]
              exten => [email protected]

<mailto:[email protected]>,1,Verbose(0,

              Incoming gtalk from ${CALLERID(all)})
                    same => n,Answer()
                    same => n,Wait(2)
                    same => n,Dial(SIP/D70)
                    same => Hangup()


              I would appreciate if anyone could give me a hint
about

the

              audio path.
              This is a project that we I will try to setup in a
small

fire

              department, and before I try it, I would like to
make sure that

my

              Digium phones will be able to get full audio path
behind

private

              networks.

              Thanks a ton for the help !
