[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?

Re: [OSL | CCIE_Voice] Gatekeeper Call Routing
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. BTW can you send this output? *show gatekeeper zone prefix* ** ** On Thu, Nov 17, 2011 at 4:30 PM, datucha123 datucha123 datucha...@gmail.com wrote: Hello everyone. I have a question about the GK.

Hi , Gatekeeper will route the call without Zone prefix if all the endpoints are registered in the same zone.

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?
