[asterisk-users] Google voice with no voice

Tue Jan 22 10:21:59 CST 2013

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