Re: [Freeswitch-users] google voice connection going offline (mod_dingaling)

8 Oct 2011

      Hi Anthony,

thanks for the clarification and the suggestion. As an immediate
workaround I would like to try the "cron" approach you suggested. I
have therefore experimented a little bit with the chat api command.

My jingle_profiles/client.xml looks essentially as the one provided
with the example configuration:

  <profile type="client">
    <param name="name" value="$${xmpp_client_profile}"/>
    <param name="login" value="user1@gmail.com/talk"/>
    <param name="password" value="XXXX"/>
    <param name="dialplan" value="XML"/>
    <param name="context" value="public"/>
    <param name="message" value="Jingle all the way"/>
    <param name="rtp-ip" value="$${bind_server_ip}"/>
    <param name="ext-rtp-ip" value="auto-nat"/>
    <param name="auto-login" value="true"/>
    <!-- SASL "plain" or "md5" -->
    <param name="sasl" value="plain"/>
    <!-- if the server where the jabber is hosted is not the same as
the one in the jid -->
    <param name="server" value="talk.google.com"/>
    <!-- Enable TLS or not -->
    <param name="tls" value="true"/>
    <!-- disable to trade async for more calls -->
    <param name="use-rtp-timer" value="true"/>
    <!-- default extension (if one cannot be determined) -->
    <param name="exten" value="888"/>
    <!-- VAD choose one -->
    <!-- <param name="vad" value="in"/> -->
    <!-- <param name="vad" value="out"/> -->
    <!--<param name="vad" value="both"/>-->
    <!--<param name="avatar" value="/path/to/tiny.jpg"/>-->
    <!--<param name="candidate-acl" value="wan.auto"/>-->
    <param name="local-network-acl" value="localnet.auto"/>
  </profile>

When I try to use the chat command at the fs_cli prompt I'm unable to
form a full jid and always get an error message from the remote
server. Here an example:

chat jingle|888@xmppc|user2@gmail.com|test

  </error>
</message>

"xmppc" is the value of the variable "xmpp_client_profile" as in the
default config. I get the same error independently from what I set
before "@xmppc" in the from_jid. Differently from this, if as the
from_jid I set my explicit jid "user1@gmail.com/talk" as in the
client.xml file I get the error:

2011-10-08 14:20:50.446696 [ERR] mod_dingaling.c:544 Invalid Profile gmail.com

Despite the fact that even a wrong message reaching the remote server
could work as a "keep alive" signal, I still would like to understand
the proper syntax.
I would be grateful if somebody could explain me what is the correct
syntax to use with chat and jingle?

Thank you!
Fede

P.S.: By the way, I'm now working on HEAD.

One option would to have a NAT that doesn't disconnect active
connections just because they are idle (which seems bad to me).
Otherwise you could work on a patch, request a feature or come up with
some cron job maybe to use the chat api command to send a message to
your server from cron or something as a workaround.

The git version I'm running is from the 20th of August. In the mean
time have there been changes which could affect mod_dingaling? Looking
in the git commit comments I have the impression that the answer is
no.

Just in case someone will hit the same problem...
After some tests, I've found that, changing "bind_server_ip" from
"auto" to the local IP address of the FS server (192.168.X.X), appears
to solve my timeout problem.  (The account did not go offline for more
than 12 hours.)
To summarize my current configuration: I have a fix public IP assigned
to my router (NAT/Firewall). NAT is configured to forward ports 5080
and 5081 to the host on which FS is running and UPnP is disabled.
I'm running a FS version checked out from git the 20th of August.

The only thing I can say is to update your FS with the latest git commit.
