asterisk users - Jun 2015 - Connecting two Asterisk

Hi again!

I always try to get my mobile phone work with my Asterisk.
I tried to install Asterisk on my PC (with public IP), but it has problems,
too...
I think, my UMTS-Provider doesn't want to connect to dynamic IP or my
DSL-Provider
does not want it, too, since I have no problem to connect and get a very good
audio quality if I connect to other SIP-Provider or to an Asterisk (SAME
configuration!!) installed on my Server...

Well, I will try to configure the Asterisk on my Server to act as
"proxy" so
that all phones at home talk with my Asterisk at home (now called
"wrt", and
my mobile phone talk with my Asterisk on my server (now called
"lucabert").

I followed this HowTo http://sysmagazine.com/posts/125303/ and I got both
Servers talking together.

I can call my mobile phone (logged in at "lucabert") from a phone
logged in
on "wrt" and a phone at "wrt" from my mobile phone at
"lucabert".
Wonderful!

Now the problem: on my phones at "wrt" I can hear what the mobile
phone at
"lucabert" sends (with a very good audio-quality), but on this mobile
phone
I cannot hear a single word spoken with the phone at "wrt", not even
the music
on hold I configured...

When I call my mobile phone from a phone logged on at "wrt" I see on
the
Asterisk at "wrt":

On the Asterisk at "lucabert" I see:

Well, I'm very puzzled...
Can someone help me?

Thank you very much!

Some other data...

I changed both iax.conf and wrote:

bandwidth=high
allow=all

Now I see in the log:

       > requested format = ulaw,
       > requested prefs = (),
       > actual format = ulaw,
       > host prefs = (),
       > priority = mine

and I can hear somewhat, but with a VERY poor quality on my mobile phone...
On the other phone however, the quality is very good...

I'm very very puzzled...

Thanks for any help!

Maybe fiddling with the SIP and RTP ports would help.

I thought GSM regurgitated by cell had issues. Can you try alaw/ulaw?

Yes, I do, but the quality is always very poor...
