[OSL | CCIE_Voice] Gatekeeper Call Routing
Hello everyone. I have a question about the GK. I could not understand how does the GK knows where to route call based on the following GK configuration: gatekeeper zone local test test.com 177.1.254.1 gw-type-prefix 1#* default-technology no shutdown CUCME and CUCM, both are registered with the Tech prefix: R1#sh gatekeeper gw-type-prefix GATEWAY TYPE PREFIX TABLE = Prefix: 1#*(Default gateway-technology) Zone test master gateway list: 177.1.254.3:1720 CME 172.16.4.121:35498 CM_2 172.16.4.120:37425 CM_1 So the CUCME has extensions 3... and CUCM has extensions 2... Basically, the calls are working fine between CUCM and CUCME through this GK. But I cannot get the idea, how does the GK know where to route calls (CUCME and CUCM IP Phones are not registered with GK). For instance, when the CUCM calls number 3003 (this is CUCME IP Phone), the ARQ request is sent to GK, and at this point, how does the GK knows whos IP address to return in ACF message to CUCM? How does the GK get that the the CUCME IP address must be sent to CUCM? There are not zones prefixes configured. Can anybody explain that to me? ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Pls check the call routing diagram here , which has explanation. http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a00800a99c4.shtml (Call Routing solely use tech-prefix here) Some steps are not very descriptive , no explanations available as well.

Re: [OSL | CCIE_Voice] Gatekeeper Call Routing
There are no Zone Prefixes defined, As for endpoint, only the CUCME and CUCM H323-IDs are registered, NO CUCME IP PHONES. CUCME and CUCM are registered also with the defaul Tech prefix. But based on the config, there are two endpoints (CUCM and CUCME) registered with Default Techs, So how does the GK knows where to router calls, if there are not IP Phones registered with GK, and also two Endpoints (CUCM and CUCME) are using the default Tech prefix?

Re: [OSL | CCIE_Voice] Gatekeeper Call Routing
gatekeeper will not send calls back out the sending trunk; so calls from CME are fine, and usually calls from CUCM are fine but when we have two CUCM trunks registered there is a risk of calls leaving one CUCM trunk and trying to send the call to the other. hth On Thu, Nov 17, 2011 at 7:42 PM, Bill Lake whl...@gmail.com wrote: Can we see the output of show gatekeeper endpoints?

Re: [OSL | CCIE_Voice] Gatekeeper call routing between BR2 CME and BR1 H323 gateway
Hi Vik, Thank you for your input. I saved my configurations for this lab, and have been working on the +dialing lab 10, so let me revert back to this lab tonight and try your suggestions. I remembered I did unchecked the Outbound Fast Start at one point during troubleshooting, but it did not make any improvements. I will try again tonight and reply back with results as soon as I can. Thanks, TN. ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
Re: [OSL | CCIE_Voice] Gatekeeper call routing between BR2 CME and BR1 H323 gateway - RESOLVED
Hi Vik, It was not a problem with codec, mtp, nor outbound fast start; it was the problem with database and the UCM cluster. I reverted the database all the way back to phone configurations only, no trunk configured, and then set up the trunk and gatekeeper and everything started working fine. Now I have tried with or without enabling outbound fast start and either way it works just fine. Thank you for your input anyway.

Re: [OSL | CCIE_Voice] Gatekeeper call routing between BR2 CME and BR1 H323 gateway
It seems codec related if the call works between HQ-CME and not between BR1-CME. Can you uncheck outbound FastStart in the GK ICT and see if that helps? Can you also report on the codec listed in the dspfarm (sw MTP) on the HQ-RTR and also in the dial-peers on the CME (both incoming from GK and outgoing to GK). Inbound FastStart is required on the GK ICT for calls from SIP Phones on the CME. You shouldn¹t need outbound FastStart in the reverse direction unless you are specifically wanting to test this. -- Vik Malhi CCIE #13890 Managing Partner / Instructor - IPexpert, Inc.

HQ and BR1 phones in UCM both SIP and SCCP. BR2 is CME and has both SIP and SCCP phones as well. The gk-trunk has MTP (IOS software on HQ) checked, Inbound and Outbound Faststart enabled. Calls between HQ and BR2 CME, including TEHO, are working for both SIP and SCCP phones. However, calls between BR1 and BR2 are not working at all.

So I made a 'valid test' like this: configure a CIT RP (pt-internal, dp-BR1 as normal BR1 dn), and set CFAll to 5002, and call from CME to this DN worked fine. So I think there some codec or MTP issue when routing call from CME to BR1 actual IP phones. With that in mind, I configured Xcoder on all the sites, but calls still failed between CME and BR1 H323 site via gatekeeper. One thing in mind that I checked the scenarios in both Vol1 and Vol2 IPExpert and none of them have this call routing scenarios. A couple labs have HQ-H323, BR1-MGCP, and BR2 CME, but none of them have BR1 as H323 gateway with gatekeeper routing in the mid. So I wonder why IPexpert did not cover this scenario, and if my testing scenarios is a valid test or not, and if not, why?
