Hello, I'm working on upgrading all 7942s (near end of life phones) with 8851s.  My call center phones were easy, I used the Bulk Admin Tool to use a template to insert the phones into call manager, with ext mobility, we distributed the phones, agents log in to them with their Device Profile, and every thing is good. That was easy because there isn't one specific user for the phone, they could all be generically inserted.  The rest of the 7942s we need to replace belong to specific people, so there will be a one to one swap, the 8851 coming in needs to have the same extension(s), line displays, ASII displays, masks etc. that the 7942 had, some people have two extensions, some have one.  The template for the generic agent phones was simple, I just don't know how I'm going to ensure that everything gets moved over to the 8851s that was on the 7942s.   I've seen a few guides, but they get confusing because there are so many if/thens that it's hard to tell what exactly applies to me.  Does anyone know of a good guide specifically for the situation I described above?   Thanks ...

CUCM System version: 11.5.1.14900-11   Hello, I am planning a firmware upgrade for my 8841/8851s.  I will be upgrading them to sip88xx.12-0-1SR1-1, which I have uploaded to the TFTPs and I have successfully upgraded one single phone, and it is working well.   When I go to Device -> Device Settings -> Device Defaults, the active load for 8851 is sip88xx.10-3-1-20, which is what most of our 8851/41s are using with the exception of some newer ones that require 11-7 or higher, which came shipped with that version of firmware.  The inactive load for 8851/41s shows sip88xx.12-0-1SR1-1, which is the firmware version I want to update to.   I had expected that if I went to any 8851 in call manager that it would show 12-0-1SR1-1 as the inactive load on the phone.  My understanding was that once I put the new firmware on the TFTPs, the new version would be sent to the inactive bank of all 8851/41s.  Should I be concerned about this for my firmware upgrade?  I'm just not sure if when I swap the loads in Device Defaults if that is when the newer firmware will be sent to the phones, or if it should be sending the new firmware out to the phones to the inactive bank, so that when I Swap Loads, it's already ready on the phone already.  Or if  I should just expect it to take a while when I do the upgrade because it will still have to send the firmware out to all the phones.   Thanks ...

CUCM System version: 11.5.1.14900-11   Hello, We received our AT&T bill and there's $2,400 international off-net charge.  I'm trying to figure out who made the call.  The number listed on the bill is 775-900-0000, which has a Nevada area code, we are in the United states, so it doesn't seem like that should be an international call (but that's not the issue at hand right now).   I thought it would be as simple as searching CDR for the phone number.  But, I've searched a year's time span for the number and there is no record of it ever being dialed. Also, the bill doesn't give handy info like exactly when the call was made.   Does anyone have any idea how I can track this call down in CUCM?   Thanks ... View more

Hello,   I'm working on a CUCM migration. Source Cluster: CUCM 9.1.2.14900-14 Migration Cluster: CUCM 11.5.1.14900-11   Both clusters are up, the source cluster (9.1) is still in production, the plan is to switch over to the migration (11.5) cluster this Sunday.  I'm following this post here: https://community.cisco.com/t5/collaboration-voice-and-video/migrating-ip-phones-between-clusters-with-cucm-8-and-itl-files/ta-p/3108501   Mainly the "Bulk Certification Export" sections since that is what I will be using for the cutover.  It says to use DHCP option 150 so the phones can check in at the new cluster, verify against TVS, which replaces the ITL file, and the phone registers to the new cluster.   At this point, I don't want all phones to move over, so I don't think I want to change DHCP option 150 until I'm ready to move all phones to the new cluster.   On the 8841 I'm trying to move to the new cluster, I can go to Settings -> Admin Settings -> Security setup -> Trust list -> ITL file and see the signature, the TVS's the TFTP server like expected.  But what I was expecting to see here was the ability to put in the new Publisher's address so the phone can find it. I suspect that is what DHCP option 150 does for all of the phones, but how do I do it with just one single phone?  I thought maybe the settings were locked, so I tried **# to see if anything would unlock, but it didn't appear to.   Also, at this point I haven't consolidated the certificates, but I am assuming I will need to do that before I attempt to migrate the phone to the new cluster.   Any info anyone has would be greatly appreciated. Thanks in advance! ... View more

Hello all, I'm currently working on a project to upgrade CUCM from 9 to 11.  It turned in to a migration project instead of an upgrade because we wanted to put CUCM 11 in new address space.  I currently have the migration done, so CUCM 9 is still in production, CUCM 11 is off in the new space and is an exact copy of the CUCM 9 environment.  The last step in this project is to put CUCM 11 into production and shut down CUCM 9.  I have a TAC case open, but I'm looking for input from people who have done this before.  What I'm currently dreading is the gateways.  I'm going to have to get the gateways registered in the new call CUCM 11 and I'm going to have to get the phones to check in with new CUCM 11.   My PCD migration task is currently paused after the migration, the next tasks are to shut down each node in the cluster, which I haven't continued because the actual switch over to the new CUCM 11 won't be until a week an half from now.   I'm just looking for any advice on the timing of all of this.  I believe I will need make changes to the new CUCM11 configs to get the gateways to register in the new call manager, and I also believe I will need to do something with the phones to make them check in and register with the new CUCM 11. And I believe this will need to be done within the window of time I have to make the switchover to CUCM 11. I'm just hoping to find someone who can give me an idea of what to expect and how they timed it out when they were making the cut over.   Thanks in advance   There's a ton of info out there but it's tough to find the right info and I just wanted to see if I could get some advice from someone ...

Hey Everyone,   We're using UCCX 10.6 and CUCM 9.1. We had an issue where all UCCX agents' active calls were dropped and all agents were kicked out of CAD; they use ext mobility, but did not have to log back in to their phones.  Agents were able to log back in to CAD and continue taking calls.   I don't believe it's a CUCM issue because non-queue phones didn't drop calls and we're transitioning from UCCX to a new call handler.  Agents who use the new call handler had no issue at all and lost no calls.   I'm not even sure where to begin to try and figure out what happened.  I didn't have RTMT up and running while it happened, so it probably won't be much help.   Also, my UCCX publisher shows "partial service" now.  I'm not sure if the publisher died out and now the subscriber took over...could be why everyone dropped and had to log back in.   What can I look into to try and figure out what happened to make all of the agents lose their calls and get logged out?   Thanks in advance. ...
