Config 2811 as a gatekeeper for VideoConf-h323

Got a 2811 with the SipServices/h323 IOS. I need to setup the unit as a gatekeeper for 6 polycom HDX 7000 endpoints. Gk will only used for video conferencing, no Sip. Can someone point me to a sample config for the 2811 or somehting? Searching for "gatekeeper" didn't turn up anything helpful.

Thanks

If Brandon's links aren't enough, shoot me an email address; I'm using 2811s for core GK (and alt) and can send you my config as a starting point and/or comparison.

Re: Config 2811 as a gatekeeper for VideoConf-h323

Hi robert

I have two gatekeepers (MCM-cisco2621mx, with ios 12.3 jsx)

the configuration of GK is:

gatekeeper

zone local GK mio.com

zone remote GK2 otro.com 192.168.10.10 1719

zone prefix GK 226....

zone prefix GK2 5....

gw-type-prefix 1#* default-technology

lrq forward-queries no shutdown

!

the second gatekeeper (GK2):

gatekeeper

zone local GK2 otro.com

zone remote GK mio.com 192.168.210.85 1719

zone prefix GK 226....

zone prefix GK2 5....

lrq forward-queries

no shutdown

!

i have two terminals H323, one register on the GK (zone 226) and other on the GK2 zone (5)

So, when i call 2267721 or 52345 the call not connect.

I need your help please.

Sincerely thanks!!!

I'm in the same boat as you, here is a link to some gatekeeper info.

http://www.cisco.com/en/US/docs/ios/12_2/voice/configuration/guide/vvf323gk.html

Hopefully the 'Starting a Gatekeeper' and 'Configuring a Gatekeeper Example' sections will be helpful.

Re: Config 2811 as a gatekeeper for VideoConf-h323

Thank you for the information, I do have a question, which IOS version are you using on your 2811 router?

Re: Config 2811 as a gatekeeper for VideoConf-h323

That guide is for 12.2 IOS. 2811's run 12.4 out of the box. Commands have changed some since 12.2. you can't paste in some 12.2 gk commands directly into 12.4 from what I remember.

Can anyone tell me why is it so hard to find Cisco IOS guides? The old "Cisco Connection site" made it easy to find IOS guides. Still can't find an easy way to find all the IOS guides for IOS 12.4/12.3. What am I missing here?

Re: Config 2811 as a gatekeeper for VideoConf-h323

I'm running release 12.4.23, specifically c2800nm-adventerprisek9_ivs-mz.124-23.bin

Some of the commands may be different since the guide is for 12.2, however, the 'Starting a Gatekeeper' and example commands appear to be the same.

That is the IOS that I am running, have you run into any licensing issues, from what I understnad the gatekeeper requires licenses after 12.4(20)T.

Re: Config 2811 as a gatekeeper for VideoConf-h323

Is their any gatekeeper security we can implement, so we do not have just anybody joining the gatekeeper on our network?

Re: Config 2811 as a gatekeeper for VideoConf-h323

Hello:

You can use the command:

zone subnet zonename ip_address_range enable

Only the endpoints in this range can register in the gk.

You can use AAA too.

regards
