Re: [OSL | CCIE_Voice] Gatekeeper is unable to reach SiteB under Call Forward UnRegister
Dear Hesham, As far as I understand from your email, SiteB is now in SRST mode, which means that SiteB WAN connection is down. In this case, SiteC won't be able to reach SiteB phones over the WAN through GK but you will have to configure a lower preference dial-peer to reach it through PSTN in case the GK rejects or can't reach SiteB phones.

Re: [OSL | CCIE_Voice] Gatekeeper is unable to reach SiteB under Call Forward UnRegister
Hi Hesham, I have a few ideas. I want to remove a few things out of the equation, first try to set codec for all inter-region to G711. Second, if you are using Local Route Group (LRG), replace it with a more straightforward settings -- i.e. point the RL directly to HQ gateway in your case for relevant route pattern. We can deal with them later on once we understand this case to the bone. There are two call legs. The first call leg is from SC PH1 to reach x3001 via a H323 Trunk on CUCM -- the Trunk with gatekeeper control. The call should be directed to the gatekeeper who in turn should be routing it to the H323 Trunk on CUCM. The H323 Trunk should have significant digits set to 4 and a CSS that can reach x3001. Upon hitting x3001, CUCM will discover that the number is forwarded to 9723033001. Assuming that you have set the CSS for CFUR on x3001 correctly, that will match a Router Pattern that route the call toward HQ Gateway.This is a second call leg.(If you use the LRG, at this point, the LRG for the incoming H323 Trunk will cause the call to route to the wrong RG.) Once the second call leg is established, then CUCM will tell the two parities to open the RTP channel directly to each other (i.e. between the CME and the HQ Gateway.) (Well, sort of, if you have MTP required check on the H323 Trunk, then an MTP will be involved.) You problem could be on either one of this. While I believe that since you can make a call from HQ PH1 to x3001 successfully, the problem may not be in the 2nd leg, I don't entirely want to rule out the CSS, the Significant digits as well as the fact that HQ PH1 and the incoming H323 Trunk will be more than likely belong to a different Device Pool Region. I think debug gatekeeper main 10 on the gatekeeper would help. On the H323 CUCM Trunk, RTMT Real Time monitoring with Detailed Debug turn on would help you see whether the H323 Trunk has the right CSS to reach x3001. Hope this gives you some idea to work on this case. Regards, --Somphol.

If your CUCM SBGW happens to be in the different zones, that is a different matter. Looking at a configuration guide for zone prefix command, I don't think it is possible for a zone prefix to point to two different local zones.

I think debug gatekeeper main 10 on the gatekeeper would help. On the H323 CUCM Trunk, RTMT Real Time monitoring with Detailed Debug turn on would help you see whether the H323 Trunk has the right CSS to reach x3001. Hope this gives you some idea to work on
Re: [OSL | CCIE_Voice] Gatekeeper is unable to reach SiteB under Call Forward UnRegister
Sorry, I assume wrongly that SBGW will ever take the call for 3 Your normal path is for both 2... and 3... to be pointing to CUCMTRUNK only. Given that both SBGW and CUCMTRUNK are registered to the same zone, it would be necessary to exclude SBGW from ever getting the call destined to 2... or 3 gw-type-prefix 1#* default-technology zone prefix THEZONE 3... gw-priority 0 SBGW zone prefix THEZONE 3... gw-priority 10 CUCMTRUNK zone prefix THEZONE 2... gw-priority 0 SBGW zone prefix THEZONE 2... gw-priority 10 CUCMTRUNK Sorry for the confusion. Even if you don't have gw-priority, when SBGW is unreachable, it should not cause the problem and call should be sent correctly to CUCMTRUNK. Then, it is less likely that the problem would be in the gatekeeper call leg, unless you use some sort of tech-prefix in addition to zone prefix. Regards, --Somphol On Sun, Jun 23, 2013 at 8:43 PM, Somphol Boonjing somp...@gmail.com wrote: Hi Hesham, Essentially, the gw-priority is to advise the gatekeeper to choose SBGW over CUCMTRUNK. The higher the number, the higher the priority. Without this it will distribute the call to 3XXX to both CUCMTRUNK and SBGW in a round robin fashion. If you give higher priority to SBGW, then call will be routed to SBGW unless it is not available. gw-type-prefix 1#* default-technology zone prefix THEZONE 3... gw-priority 100 SBGW zone prefix THEZONE 3... gw-priority 10 CUCMTRUNK I'm fairly new to gatekeeper myself, so it would be great if you can lab it up and see if I am wildly off the mark.

Re: [OSL | CCIE_Voice] Gatekeeper is unable to reach SiteB under Call Forward UnRegister
Calls work when he is not in SRST so 3... must be sending to CUCM to be processed and set to phones at site B. They are registered and work but when unregistered they fail to work. If we are going on this little snippet of his GK config we might need the entire thing and those on the GW's to figure out why this call is not working.

Dear Experts, SiteC is CME and connected with HQ and SB via Gatekeeper Gatekeeper is working excellent with HQ and SB I am configuring Call Forward Unregister for SiteB.
