asterisk users - Feb 2007 - ooh323 drops registration with Cisco IOS GateKeeper - bug or config issue?

All,

I'm running (attempting to) ooh323 with Asterisk and a Cisco 2621XM router
operating as a H.323 GateKeeper, however when I bring the Asterisk box up it
registers successfully with the GateKeeper (exchanges GRQ/GCF, then RRQ/RCF) it
notes the GateKeeper supports keepalive at 300 seconds, when it gets to time to
re-register its sends an RRQ again and gets rejected with RRJ (unspecified
reason) and so closes the session.

At this point the H.323 session is lost and never retried.

The set up is as follows:

    Asterisk Box: RedHat/Fedora Core 3, Asterisk 1.2.14 (built from source),
ooh323 rev 0.8.2 from Asterisk-Addons-1.2.5

    Cisco GateKeeper: 2621XM router with c2600-jsx-mz.123-22.bin

Config on Asterisk box:


; Objective System's H323 Configuration example for Asterisk
; ooh323c driver configuration
;
; [general] section defines global parameters
;
; This is followed by profiles which can be of three types - user/peer/friend
; Name of the user profile should match with the h323id of the user device.
; For peer/friend profiles, host ip address must be provided as
"dynamic" is
; not supported as of now.
;
; Syntax for specifying a H323 device in extensions.conf is
; For Registered peers/friends profiles:
;        OOH323/name where name is the name of the peer/friend profile.
;
; For unregistered H.323 phones:
;        OOH323/ip[:port] OR if gk is used OOH323/alias where alias can be any
H323
;                          alias
;
; For dialing into another asterisk peer at a specific exten
;       OOH323/exten/peer OR OOH323/exten@ip
;
; Domain name resolution is not yet supported.
;
; When a H.323 user calls into asterisk, his H323ID is matched with the profile
; name and context is determined to route the call
;
; The channel driver will register all global aliases and aliases defined in
; peer profiles with the gatekeeper, if one exists. So, that when someone
; outside our pbx (non-user) calls an extension, gatekeeper will route that
; call to our asterisk box, from where it will be routed as per dial plan.

Any ideas whether this is a bug or a configuration issue?
