[OSL | CCIE_Voice] AAR Not Attempting to ReRoute
All, Hopefully someone can give me an idea on this one. Working on my own equipment but following the labs and am running into an issue with AAR. I'm sending a call from HQ to BR 1 using 4 digit dial 5002 --- 1002. When I attempt to make the call I receive the message Not enough bandwidth, however I never see AAR actually get invoked. In my setup as a quick way to simulate congestion I set the bandwidth to 23 Kbps between Hub non (hq) and BR1. When I place the call from HQ as I said I get the banner of not enough bandwidth but I never see the call actually hit the HQ gateway. I've run debug voip dialpeer, q931 as well voice ccapi inout and neither shows any sort of traffic hitting the gateway. In testing I can successfully dial into the HQ GW, I can dial emergency services from the HQ phone, just doesn't seem like it's ever invoking AAR. I also checked that the external number mask is correctly defined on the 1002 extension. AAR CSS is assigned to the HQ phone, AAR group is assigned to the HQ line. AAR group is prefixing 91 and there is a RP assigned to a partition that falls within the AAR CSS that is for 91617XXX that has a RL pointed to the HQ GW. I did see earlier in the lab that they recommend using 7962 phones, however I don't have any avaialble at the moment, so just wanted to make sure that this might not be it. Any help would be much appreciated. Thank you ___ 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] Lab 4A BR1 MGCP Issue
Thanks, removing the l3 bind, doing a shut, no shut on the serial interface then adding the l3 bind statement back in did it. Thank you, much appreciated.

[OSL | CCIE_Voice] 7960 CUCM SIP Registration
All, Having an issue with a 7960 registering to CUCM using SIP. On the actual phone itself keep getting the error registration rejected. Within CUCM I also see rejected on the phone page. I've verifed multiple times that the MAC address is correct and my SIP profile is pretty basic as there is no security applied to the phone itself. This should be something that's really simple as I have other SIP phones registered to the cluster (not type 7960 though). If I register the same phone via SCCP it works fine. Also, have tried to convert from SCCP to SIP using the BAT tool; all with the same results. Has anyone else seen this or have some additional input into what may be happening?

Re: [OSL | CCIE_Voice] 7960 CUCM SIP Registration
Thanks all, it was firmware. Forgot to mention before that I had made sure there was an extension and had checked replication as that was my inital thought as well. Appreciate the assistance.

I had a lot of old 7960s on hand and ran into the same issue. Basically had to try earlier and earlier revisions of SIP firmware to get them to work. There's release notes on CCO for 7960 describing compatibility for SIP firmware 8.7. http://www.cisco.com/en/US/products/sw/voicesw/ps2156/prod_release_notes_list.html I had to go back all the way to v3 SIP firmware to get mine particular ones working. Not sure why, but those phones were made so long ago, there were likely different hardware revisions. This guide has much good info and eventually helped me get them registered w/ SIP: http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a0080094584.shtml Thanks On Wed, Jul 17, 2013 at 9:17 PM, Alex Pishko alexpis...@yahoo.com wrote: All, Having an issue with a 7960 registering to CUCM using SIP.

[OSL | CCIE_Voice] All Labs Table and Proctor Labs Vlahs
In setting up my sessions I've noticed the it doesn't appear that when you pre-load the configuration the proctor labs vlans match up with the vlan naming convention as to what's in the all labs table on the ipexpert site. Such as in all labs table hq server vlan is 30, but on preloaded config vlan is 103. Ip subnet matches up but vlan ID does not. Is this by design? If so, should I chang the vlan tag in the actual lab?
