<DIV><FONT face=Arial size=2>A couple of weeks ago I posted a problem report
regarding ooh323c (used with Asterisk) and re-registration with Cisco IOS based
Gatekeepers (and possibly other Cisco GKs) whereby the initial registration
would succeed, but re-registration would fail.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>After some investigation I found that the problem
was that Cisco implement (expect) a light-weight re-registration RRQ message
that has KeepAlive set and has the GateKeeper's end endpoint identifier returned
in it - all the other parameters are ignored and according to Cisco do not need
to be present in a re-registration because parameter changes are not
permitted.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The attached patch fixes the problem (for me -
YMMV) with ooh323c version 0.8.2 as shipped in Asterisk-addons-1.2.5.tar.gz by
modifying the ooGkClient.c module so that it </FONT><FONT face=Arial
size=2>determins whether the registration is an initial registration (without
endpoint identifier) or a re-registration in which case the GK's endpoint
identifier is added to the H225 RAS RRQ message. All of the other parameters are
still passed (unchanged).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This has been tested with a Cisco 2621XM router
running IOS H.323 GateKeeper (router firmware c2600-jsx-mz.123-22.bin) and works
fine - it needs testing on other H.323 GateKeepers that implement (require)
light-weight re-registrations...</FONT></DIV>
