<p class=MsoNormal>Recently, I’m trying to resolve a issue with Ricoh fax
machine using H323 to Callmanager. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>From Ricoh’s sample diagram, they have included a
gatekeeper in the topoloy. My colleague has been trying with TAC on this issue
for a few months (without a gatekeeper) and it seems like there’s no
progress. <o:p></o:p></p>
<p class=MsoNormal><br>
Ricoh Fax <---h323--- > CUCM <---mgcp ----> PSTN <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We are not going to modify the voice gateway side using mgcp
as we have xmedius IP fax working on it. I just happened to take over this project
while he’s away. I decided to try my luck using a gatekeeper. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>While desperately looking for a cisco router to run IOS
gatekeeper, I used a temporary solution due to time constraint. GNU
gatekeeper(3<sup>rd</sup> party) was chosen. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The call fails initially till I enabled H245 routed mode. It
works fine however it’s 3<sup>rd</sup> party solution which will not be
supported by anyone in the future if it stop working somehow. We are switching
back to Cisco GK as we found a extra voice gateway. While researching, I found some
comment online that IOS gatekeeper doesn’t support GKRCS. Is this true?!<o:p></o:p></p>
