Grasshopper,
You have your first clue, the live test works.
Do you understand how SIP works? During the INVITE sequence the Asterisk
and the phone trade RTP CODEC information. RTP is the protocol that
actually carries the sounds, SIP only does the handshaking for the call.
A CODEC is what the RTP is carrying between the pones.
If you do "sip debug" inside of the asterisk command line interface
*CLI> sip debug
Then you will see the SIP Messages and the Codec agreements.

Asterisk is the " us - 0x8000e (gsm|ulaw|alaw|h263)"
Phone is the " peer - audio=0x10e (gsm|ulaw|alaw|g729)"
Above is the trace of my SNOM 200 -- see the "combined - 0xe
(gsm|ulaw|alaw)"?
The phone can do g729, but asterisk can't, so asterisk and the phone
agree on a non-g729 codec, ulaw.
Eventually the phone agrees to "a=rtpmap:0 PCMU/8000", it is going to
talk sound using ulaw at 8000hz. (again, I might be a little wrong on
the extact details.)
If the phones agree to use G729 then the playback won't work because you
don't have a g729 license, $10 from Digium.
Remember that asterisk is a third party to a conference and if your
conference is using g729, then asterisk can't do that.
In the sip.conf,
Disallow=all
Allow=gsm
Allow=ulaw
Allow=alaw
This will force the phone and asterisk to speak gsm, ulaw or alaw.
I had the same experience with no sound when I first connected a Cisco
7960, I could here other people, but not the prompts. Asterisk will
allow G729 to pass through, but it will not allow G729 to originate and
terminate without the license (I might be a little mistaken here...)
I hope this helps. I have not use [EMAIL PROTECTED], it might be different.
Let me know,
Race "The Tyrant" Vanderdecken

Hi Race..
In this case, the asterisk|home comes preconfigured with some stuff
different than the asterisk tar file.
I check and the phone supports all mentioned codecs, I also made a test
by
using the phone and sjphone to do a live test directly, conversation was
successful using gsm, ulaw and ilbc.
Any other ideas?

Okay,
A couple of things could be happening so let's run through a list. Your
questions are a little vague so I shall make my answer also vague.
1. Codec.
Are you allowing for and does the "phone" support the codec that
the
sounds are in? (I.e. do you have a G.729 license for your Minkey?)
2. Does the phone support the G.711a/u law that I think the sounds come
in?
3. Test first the voicemail playback demo and make sure you can here the
sound there before jumping into a conference. Dial extension 500, do you
hear anything?
4. Is your phone working? Have you made a call to a live person?

I just installed [EMAIL PROTECTED] to see how it works and seems there is a
problem with sounds... I dont hear any announcements or recordings...
sounds
are on /var/lib/asterisk/sounds and the logs show this:
-- Created MeetMe conference 1023 for conference '8200'
-- Playing 'conf-onlyperson' (language 'en')
But I dont hear anything... any experiences with this kind of errors
and/or
[EMAIL PROTECTED]
Thx!
