Hi!

I am trying to call from my corporate network (firewalled) using Gtalk
to Freeswitch. I am not getting any audio.

In the logs I see that mod_dingaling is using my internal corporate IP
address which is not publically addressable.

2009-06-23 22:46:52.140382 [DEBUG] mod_dingaling.c:2634 using Existing
session for 4085152502
2009-06-23 22:46:52.140382 [DEBUG] mod_dingaling.c:2932 1 candidates

Candidate 146.xx.xx.xx:50320

Further on in the log, I can see GTalk sending a new candidate IP
address to use:

Because of this, I never get audio. Any ideas how to fix this?

Thanks!

try adding this to your jingle <profile> in client.xml

<param name="candidate-acl" value="wan"/>

then edit acl.conf.xml and add this list

<list name="wan" default="allow">
  <node type="deny" cidr="10.0.0.0/8"/>
  <node type="deny" cidr="172.16.0.0/12"/>
  <node type="deny" cidr="192.168.0.0/16"/>
</list>

this tells mod_dingaling that it should only pick candidates that pass the acl list given
the one we made called wan excludes all the private ranges.

If you update to latest trunk this list is created internally as "wan.auto" so you can use that
instead of making one in your config.

No it snot because of this.. you have to understand how Jingle works and if you notice it has three candidates....

Its already picked this one, maybe a packet capture would clear this up.

Also, if and when you get this working please send a message to the list. I'd like to make sure that your setup gets documented on the wiki.

Thanks Anthony.

I am getting closer. I had to put in the 146 address, which is the
firewalled address I get at work. The problem now is that when the
call is bridged, I do not hear audio.

2 scenarios:
1 -> the local extension is not registered. There is two way audio -
I hear the voicemail in Gtalk and I can leave a message which can then
be played back.
2 -> the local extension is registered. There is no audio

In my incoming dialplan I am doing this bridge: <action
application="bridge" data="user/1000@${domain}"/>

It bridges okay, the phone rings, but there is no audio.

On a side note: Isn't putting the candidate-acl list a temporary
measure? When I travel, I will most likely get a different internal
company IP address that does not start with 146. Isn't there a
smarter way for dingaling to know that there is no RTP packets being
received and then modify which candidate should be used?

Thanks!
