[Freeswitch-users] Dingaling: using a hostname instead of stun for rtp

[Mark Campbell-Smith]

Hi!

I have a hostname set in vars.conf.xml for the parameters
external_rtp_ip and the external_sip_ip instead of the usual stun.  I
found that stun was timing out and was causing some problems.  And as
I have a hostname, it makes sense to use that instead of relying on
stun.

However, when I use Dingaling, I see the following error message in
the dl_debug tracing:

<iq to="<FS_EMAIL>@gmail.com/gtalk77BBCB94" id="344" type="error"

    <sta:text xml:lang="en"
xmlns:sta="urn:ietf:params:xml:ns:xmpp-stanzas">candidate has address
of zero</sta:text>
  </error>
</iq>

Is Gtalk expecting an address in this field '<ses:candidate name="rtp"
address="host:<hostname>"' instead of a hostname?  Or should FS be
sending the hostname only and not host:hostname?

Thanks!
