Take a look at this URL. It has good information about setting up proxy feature:

I hope that helps.

Hello ,
Here is what you have to do in order to enable proxy feature on your Cisco GK:
proxy h323
interface FastEthernet0/0
h323 interface
h323 h323-id cisco@cisco.com ( for example)
h323 gatekeeper id data ipaddr x.x.x.x for example
h323 t120 bypass
then you define on which remote zone the proxy will be checked or used like that undre Gatekeeper config mode )
use-proxy data remote-zone ( remote zone name ) inbound-to gateway
use-proxy data remote-zone (remote zone name ) outbound-from gateway
Hope this help
Jacob.

h245 tunnell disable - Cisco/Vocaltec

I have an incompatibility issue between a Voice Gateway Cisco 3640 and a Vocaltec Gateway.
The Workaround from BUG CSCdz06060 tell to use the hidden command "h245 tunneling disable".
This command is a global configuration command and Cisco has no sufficient information about his impact on Router.
Is there someone with additional information about this issue?
Thanks

Bandwidth for VoIP H323 signaling channels
fsoffia - NETWORKING ENGINEER, SET SRL

Hallo
I have a VoIp application between two LANs connected by FR WAN.
I use two cisco1751 routers as gateway.
I would use LLQ and other QoS features on cisco gateway to prioritise VoIP streams.
access-list 100 permit udp host 192.168.1.1 host 192.168.2.2 range 16384 32767
access-list 101 permit tcp host 192.168.1.1 host 192.168.2.2 eq 1720
!
!
class-map voip-media
match access-group 100
exit
!
class-map voip-signaling
match access-group 101
exit
!
policy-map qos-voip
class voip-media
priority 12 (* number of VoIP channels)
class voip-signaling
bandwidth XXX
class class-default
fair-queue
!
Using g.729a codec and vad.....I would reserve 12kbps for each VoIp media channel (RTP) in the strict priority queue.
How many bandwith must I give to VoIP signaling (RTCP, H225) for each voIp channel ?
thankyou

With G.729 codec & Voice payload of 40 bytes, VAD, cRTP, FRF12, you need 6.3kbps bandwidth.
Here is the excellant url which talks about Per Call Bandwidth Consumption for VoIP calls for different media.
http://www.cisco.com/warp/public ... bwidth_consume.html
Based on that you can do the math for the bandwidth required.
Also here is the url which talks about QoS over Frame-relay for VoIP calls

Tejas:
I have a similar problem, I have voice over IP running over frame relay between a 7500 & a 3600 router. Doing DTS on the 7500
side. Everything works fine but when I try to use rtp compression to save some bandwith..it seems like "even though the
command for rtp header-compresion are accepted on the interface configuration" Compression is actually not happening.
Monitoring through EMCOM..sindle takes about 32K..i am suspecting that due to DTS on 7500 side..I am missing something....
Is there any good url ..you can suggest me....As far as enabling rtp header compression is concerned it is very straight
forward...the requirement is that ditsributed CEF be enabled globally & interface level which I am already doing...

I too have observed similiar problem as above when I was using different series of routers.But when I connected 1751 routers
at both sides with rtp compression, the compression is successful.

GK CDRs

Hello,
I have put my GK in proxy mode based on a specific remote zone created on a remote GK ( my LOCAL zone is originating the
call) in order to get reliable CDRs , the setup is functionning properly , but i have noticed , referring to call active
record file of my GK, that for each call the duration in one of two call legs CDR still zero while the other call leg CDR
returns the correct duration( similar to what i have on my end GW) .
Following is what i m seeing on my GK:
1B8B : 294301237hs.1 +-1 pid:0 Answer active
dur 00:00:00 tx:7952/274596 rx:9802/341736
Proxy x.x.x.x:17934,0,0,0,0,0 endpt: unknown/0
bw: 640/500 codec: g729/none tx: 7910/267960,0/0,0/0 rx: 9736/328136,0/0,0/0
1B8B : 294301238hs.1 +1229 pid:0 Originate 96417740638 active
dur 00:05:27 tx:9802/341736 rx:7952/274596
Proxy x.x.x.x:16672,0,0,0,0,0 endpt: gateway/0
bw: 640/500 codec: g729/none tx: 9736/328136,0/0,0/0 rx: 7910/267960,0/0,0/0
what i should do to get similar duration in both call leg ?
Any Thoughts,
Regards,
Jacob.

Is it by any chance hitting the known bug CSCdu59154 ? It might also be something to do with the synching configuration
problem on the Proxy GK?

Hello,
Appologizes for delay,
what do you mean by synching configuration problem ?
my Proxy GK is a Cisco router 7206 VXR Series running 12.2(7b) Cisco IOS , is this IOS hitting by the bug CSCdu59154
mentioned ? how could i verify?
could you please elaborate on your reply ?
