asterisk users - Aug 2004 - h.323 channel problem: I hear nothing

Hi all,

I have two problems with h.323 in *

The first one is, I can call my voip-phone,
(exten  => 59305004,1,Dial(H323/${EXTEN}@192.168.0.41))
BUT, I hear nothing

in h.323 debug mode:

*CLI> Allowed Codecs:
         Table:
   GSM-06.10{sw} <1>
 Set:
   0:
     0:
       GSM-06.10{sw} <1>

 -- Making call to 59305004@192.168.0.41.
        == New H.323 Connection created.
        -- 0254416623 is calling host 59305004@192.168.0.41
        -- Call token is ip$localhost/8634
        -- Call reference is 8634
        -- Sending SETUP message
        -- Received Facility message...
        -- Ringing phone for "np210 [192.168.0.41]"
        -- Received Facility message...
        -- Connection Established with "np210 [192.168.0.41]"
        -- Received RELEASE COMPLETE message...
        -- Sending RELEASE COMPLETE
 -- np210 [192.168.0.41] has cleared the call
        == H.323 Connection deleted.

in Master.csv I see:
"","0254416623","59305004","isdnline","0254416623","Zap/1-1","H323/192.168.0.41","Dial","H323/59305004@192.168.0.41","2004-08-10
09:53:28","2004-08-10 09:53:47","2004-08-10
09:53:54",26,7,"ANSWERED","DOCUMENTATION"

So everything looks ok. Why I hear nothing?

second problem is I can't call out. my phone needs gatekeeper. Is there any
way to by-pass it, couse I read that asterisk oh323 can't work in gk mode.

THANKS for help.
