Re: [OSL | CCIE_Voice] Hyphothetical Voice Infrastructure Issue Question
Hi, Apart from checking the network infrastructure configuration. what other troubleshooting has been done? Have you verified the phone actually gets correct voice vlan? does it receive IP Address in the correct pool? does it get the TFTP server? Check the settings on the phone. If the phones does receive the correct information. then maybe the phone has previously been registered to other cluster min v8.0 ? starting v8.0 they have security by default. which means the phone downloads the ITL file, and checks the TFTP server signature in every configuration file downloaded to match one in ITL file. You can erase the ITL file through configuration.

Hi.. Firstly, are you using CUCM or CME?? Secondly, try using a Static IP on the IP Phone. (*try using a 79XX ip phone.. it is easier to know wat is happening*). Thirdly, try registering a phone with static IP in the same vlan as that of the Call Manager Fourthly, If your using CME, make sure the source-address comand is correct under the telephony-service commands. Fifthly, if your using a CUCM, delete the DHCP scope and recreate them and try Hope one of these works.. :) Cheers, Shabeeb On Thu, Dec 13, 2012 at 4:38 PM, Michael Davis wrote: > Scenario for campus intrasture problem: > > Phones are not registering.

Re: [OSL | CCIE_Voice] Hyphothetical Voice Infrastructure Issue Question
Amp and Derek have provided great advice on validating that your infrastructure is not the issue. It sounds like your phones are getting valid IP. If you are using auto-reg for your phones in UCM, I would also check the following: 1. Ensure that your Subscriber has auto-reg enabled and you have valid DNs for assignment (make sure you have enough for all phones). 2. Ensure that the Subscriber enabled for auto-reg is in a CM group that is enabled for auto-reg AND that it is first in the priority list. 3. Check your phone settings to ensure that the proper addressing, TFTP host(s), and CM hosts(s) are present. If you are still hitting issues, we may need more information on the symptoms (checking the phone display for any status messages that pop or checking the status message log from the phone).

Hey Michael, Have you checked to make sure that DHCP snooping is not turned on on the switch, as well as, check and make sure your operational vlan is being allowed on the trunk. Thanks, Amp Quoting Michael Davis : Scenario for campus intrasture problem: Phones are not registering. Phones are obtaining a valid IP address and have been erased to ensure they are getting a fresh IP address. Solutions investigated Verified VLAN's are correct and active Verified option 150 is correct in the DHCP options Verified Helper IP address is on was the voice vlan's when in different subnet TFTP and DHCP on CM was restarted. NTP was verified and CM DB replication is normal. Idea that not checkd: WAN Qos may have been enabled thereby causing phone registration issues. Am I on the right track?
