Aug 4, 2003, 12:50am PST 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 mqueres - IP DATA NETWORK ANALYST, INTELIG TELECOMUNICAES LTDA.
Aug 1, 2003, 2:23pm PST 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
Apr 10, 2003, 1:55am PST 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.
! 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
tepatel - CISCO SYSTEMS, CCIE
Apr 11, 2003, 2:25pm PST 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 http://www.cisco.com/univercd/cc ... osvoip.htm#xtocid36
Apr 12, 2003, 7:10pm PST 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...

Jul 31, 2003, 12:21pm PST 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 jacob@teltac.com - IT Manager, Teltac Inc
Jul 22, 2003, 6:25am PST 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
what i should do to get similar duration in both call leg ?
Any Thoughts, Regards, Jacob.

Jul 28, 2003, 8:03am PST 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?
jacob@teltac.com - IT Manager, Teltac Inc
Jul 31, 2003, 5:02am PST 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 ? Regards, Jacob.
amadrid - CTO, NEXT COMMUNICATIONS
Jul 31, 2003, 8:03am PST Dear Jacob:
Could you please give me an example of how setup the proxy feature on a Cisco Gatekeeper ??? and where I can find more
information regarding this feature on the Cisco WEB site.
Actually I get CDR records from a Gatekeeper without the proxy feature and I get duration only on the second call leg, but
that it's good enough in order to get the call duration.
Regards,
Alberto

How many digital voice ports can Cisco 3663 support ? jeremy.chang - ENGINEER, RINGLINE CORPORATION
Jul 27, 2003, 9:07pm PST How many digital voice ports can Cisco 3662 support ? They said "Medium complexity Codecs: 360 (E1)/288 (T1) and High-complexity Codecs: 180 (E1)/144 (T1) "in Cisco 3660 voice
gateway data sheet . But another document said you just configured 4E1 on a Cisco 3660 router . Which one is true ?
thusain - CISCO SYSTEMS, CCIE
Jul 28, 2003, 2:58pm PST CIsco 3662 can support up to 12 Voice T1's. You will have to have NM-HDV-2T1-48 card in all six slots which will give you 12
T1's, keepng in mind cpu and memory resources. The DSP's are populated on the Network module itself and are adequate enough
to support 288 (12 x 24) channels of medium complexity codec.

Jul 29, 2003, 1:27am PST Hi, There are some other issue except physically accepted number of voice port. http://www.cisco.com/en/US/produ ... 186a00800921ed.html page will give you better idea. Even though you can install many voice ports into a router , there is other limits you
c3620-ino3s3-mz.123-1a.bin is the ios on the router.
If any one has any idea, please let me know.

VoIP Call counters (active & history) marcpere - CISCO SYSTEMS
Jul 22, 2003, 8:53am PST
I'm trying to get call count info. Basically:
- numbers of calls active - History on numbers of calls
I think it should be this MIB: CISCO-VOICE-DIAL-CONTROL-MIB.my
and those variables: cCallHistoryIndex, callActiveIndex
But I can't get from router info on those variables.
It was just enough to get calls to PSTN.
Any other variables?
Any ideia?
Thanks,
Marco Pereira CCIE # 11369

VoIP on Catalyst 6500 partsonm
Jul 22, 2003, 1:10am PST I would love to use the Cisco Catalyst switch for my VoIP implementation, linking up directly to a PABX. Is there a way of
doing it without having to use the Call Manager?
jtufail - CISCO SYSTEMS, CCIE
Jul 22, 2003, 8:31am PST Not right now. At this time the 6509 uses either a 6608 T1 blade or 6624 analog blade to talk to the CCM. It uses the SKINny
protocol to communicate with the Cisco CallManager server to set up and tear down calls. It can not work independently like a
gateway.
