Hi, There was an issue with database replication.  Phones are unable to validate certificates with TVS. Processconfig table is missing TVS port number. You can run the following command on all your TFTP servers where your phones are grabbing their config if the TVS values are missing.   run sql select processnode.name, processconfig.paramname, processconfig.paramvalue from processnode, processconfig where processnode.pkid = processconfig.fkprocessnode and (processconfig.paramname = 'URLAuthentication' or processconfig.paramname = 'SecureAuthenticationURL' or processconfig.paramname = 'TVSPort')   Should look like this   admin:run sql select processnode.name, processconfig.paramname, processconfig.paramvalue from processnode, processconfig where processnode.pkid = processconfig.fkprocessnode and (processconfig.paramname = 'URLAuthentication' or processconfig.paramname = 'SecureAuthenticationURL' or processconfig.paramname = 'TVSPort') name               paramname               paramvalue ================== ======================= =============================================== EnterpriseWideData SecureAuthenticationURL https://cucm9lab01:8443/ccmcip/authenticate.jsp EnterpriseWideData URLAuthentication       http://cucm9lab01:8080/ccmcip/authenticate.jsp EnterpriseWideData TVSPort                 2445 admin:     You can restart TVS services as a first step and check status with the previous command And if it does not solve your issue look at you database status of your cluster : utils dbreplication status If there are mismatches, do a repair from the Pub (out of heavy prod hours) utils dbreplication repair all   Hope it helps.   JC   ...

Hi Grab traces from your Right Fax server. I suppose it's a SIP integration ? Check if the Region codec used between CUCM and your SIP Fax is set to use G711 codec and not a compressed codec. ... View more

Hi, I confirm it works. Check if your camera is powered on and also your region settings. Using internet sometimes upload bandwidth is insufficient. You should create a dedicated site for VPN phones in order to manage bandwidth. At least you need 400 kbps for audio+video to have video.   JC ... View more

Hi Jason You said " TVS runs on all servers where the CallManager service is activated". I've TVS running on all the servers in my cluster despite the Publisher and 2 Subscribers TFTP dedicated have no Call Manager service running. For information, I'm running CUCM 8.6.2-23900. ... View more

IP phones can download their cnf.xml file but due to the fact that authentication url is empty, this issue occurs. Some phones have no issue, and looking at their web interface -> network setup we can see this url with the standard value. There is also no BLF presence into the call history as usual. Detail : CUCM is 8.6, phones are 8945 with latest fw I've read that IT could be linked to TVS, but which one as I'm running a 6 server cluster with dedicated TFTPs, dedicated Call Managers, Pub running only services that the others cannot.
