asterisk users - Jan 2005 - Asterisk not answering calls since oh323 upgrade

Hi

I've been running asterisk for a year or so now, and recently upgraded
to the lastest CVS-HEAD version along with oh323 v0.7.1. (previously
oh323 version 0.6.3 used to crash about once per week during high call
volumes).  Since upgrading, however, asterisk seems unable to
successfully receive h323 calls.  Previously, an incoming h323 call
would be answered by asterisk and show:

Information about active OpenH323 channel(s)
--------------------------------------------
 Num. Token                          State   Dir     Init      RX/TX  
Format       Remote RTP Addr.      Local RTP Addr.
    0 ip$210.9.89.34:44149/10136     ESTABLI BOTH    Remote   320/320 
ULAW         211.26.139.42:11544   10.152.58.222:10116

ULAW         10.152.58.220:10986   10.152.58.222:10118



Since the upgrade, I see this:

 Information about active OpenH323 channel(s) 
----------------------------------------------
 Num. Token                          State   Dir     Init      RX/TX

    0 ip$210.9.89.34:40908/9960      CLEARED RECORDER Remote     0/320
 ulaw         0.0.0.0:0             10.152.58.222:10092
    1 ip$210.9.89.34:40923/9962      ESTABLI RECORDER Remote     0/320
 ulaw         0.0.0.0:0             10.152.58.222:10098

And I cannot hear any of the sounds (IVR prompts) from asterisk.  Why
does the call Direction now show "RECORDER" instead of
"BOTH"?  Also,
nothing shows in the Remote RTP Address field.  Nothing else has
changed within my h323 network at all. Is there something new that
needs to be configured with this version?  I've looked through the
doco and nothing springs to mind.

Can anyone help?

Kind Regards
