Hello, I would like to know if there is a way to define an IPv6 source interface for DNS requests initiated from the router. The following command exist : ip domain lookup source-interface <interface> My router is in a dual-stack configuration and I would like to define 1 source interface for IPv4 DNS requests and 1 source interface for IPv6 DNS requests. Is it possible? Thank you in advance for your answer. Thomas

OK, I found why the ITL file is different. It's because I have regenerated the CallManager certificate:
"The most important certificate is now the CallManager.pem certificate. This certificate's private key is used to sign all TFTP configuration files, including the ITL file.
If the CallManager.pem file is regenerated, a new CCM+TFTP certificate will be generated with a new private key. Additionally the ITL file will now be signed by this new CCM+TFTP key."

Hello Jaime,
Thank you for your reply.
I tried to migrate one phone from one cluster to another and I had to erase manually the ITL file for the phone to work.
It's may be due to the fact that I have regenerated the following certifates : Tomcat, CallManager, ipsec, capf?

Hello,
I'm planning to upgrade a CUCM 8.5 on a MCS to a CUCM 11.5 on a UCS.
I already made the upgrade of the CUCM:
Installed my cluster (1PUB + 1SUB) on the UCS in version 8.5
Restored the backup + COP files (locales)
Upgraded to version 11.5
Installed the COP files (locales + ip phone firmwares)
I have the following migration plan:
On the current cluster, switch the "Prepare Cluster for Rollback to pre 8.0" to true -> The phones reset
On the new cluster, switch the "Prepare Cluster for Rollback to pre 8.0" to true
Disconnect from network the old cluster and connect the new one
Check if all phones register correctly
Switch back the "Prepare Cluster for Rollback to pre 8.0" to false
My question is simple : do I miss something? :)
If some people who have already done this operation can share their feedback it would be great.
Thank you.
Thomas.

Hello Manish,
Thank you!
The command "ip tftp source-interface" was indeed missing.
Now it works fine.
Have a good day.

Hello,
I'm in a lab environment and I'm configuring an ISR 4321 using MGCP protocol.
My ISR has a NIM-1MFT-T1/E1 module which is currently down (I don't have an operator link my lab).
The problem is TFTP download failed on my router :
router#sh ccm-manager MGCP Domain Name: router.local Priority Status Host ============================================================ Primary Registered 192.168.X.X First Backup Backup Ready 192.168.X.X Second Backup None Current active Call Manager: 192.168.X.X Backhaul/Redundant link port: 2428 Failover Interval: 30 seconds Keepalive Interval: 15 seconds Last keepalive sent: 19:03:03 CEST Oct 26 2016 (elapsed time: 00:00:06) Last MGCP traffic time: 19:03:03 CEST Oct 26 2016 (elapsed time: 00:00:06) Last failover time: 19:01:10 CEST Oct 26 2016 from (192.168.X.X) Last switchback time: 19:01:55 CEST Oct 26 2016 from (192.168.X.X) Switchback mode: Graceful MGCP Fallback mode: Not Selected Last MGCP Fallback start time: None Last MGCP Fallback end time: None MGCP Download Tones: Disabled TFTP retry count to shut Ports: 2 Backhaul Link info: Link Protocol: TCP Remote Port Number: 2428 Remote IP Address: 192.168.X.X Current Link State: OPEN Statistics: Packets recvd: 2 Recv failures: 0 Packets xmitted: 1 Xmit failures: 0 PRI Ports being backhauled: Slot 0, VIC 1, port 0 Configuration Auto-Download Information ======================================= No configurations downloaded Current state: Downloading XML file Configuration Download statistics: Download Attempted : 3 Download Successful : 0 Download Failed : 0 TFTP Download Failed : 71 Configuration Attempted : 0 Configuration Successful : 0 Configuration Failed(Parsing): 0 Configuration Failed(config) : 0 Last config download command: FAX mode: disable Configuration Error History:
Is that normal that TFTP Download failed if my port is down?
IOS version : 03.16.04b.S
CUCM version : 11.5.1.11900-26
Thank you in advance for your answer.

Thanks Leszek, it works! I'm affraid not to understand why it works now. Now the DTMF signals are carried as H.245 messages and before they were carried in RTP stream. We use SRTP, maybe it was the cause of the issue?

Hello,
The DTMF method has been set to "No Preference" and the trunk has been reset but I have same issue.
You can find the SDL traces attached (calling number 00634379492, called number : 6840 translated to 8400).

Hello,
Thank you both for your answer.
Manish,
I did what you told me (codec pass-through on the IOS based MTP and reset the SIP trunk associated with the MRGL) but I have the same problem. The MTP ressource is only associated to the SIP trunk, do I also have to associate it with the H323 gateway?
Rajan,
What kind of debug do you recommend?
Thomas.

Hello,
DTMF isn't working for incoming PSTN calls.
Here is the call flow:
PSTN -> ISR 4321 --H323--> CUCM --SIP--> IVR 3rd party server
The SIP trunk is configured with a MRGL containing MTP ressources (MTP ressource on GW and MTP ressources on CUCM). The DTMF Signaling Method parameter is set to OOB and RFC 2833.
I can see that a MTP is needed due to a DTMF missmatch on the logs:
|DET-MediaManager-(3189)::isMTPNeededForMismatchOrConfig, MTPNeededDueToDTMFCapMismatch(2833/OOB) mtpinsertionReason=1 dtmfMTPSide=2
But it seems there is a issue when the MTP ressource is selected:
|AppInfo |MediaTerminationPointControl(5)::SendMTPResourceErrToSender - ERROR AllocateMtpResourceReq failed -- Ci=39575083, errBitset=0x1 |SdlSig |AllocateMtpResourceErr |resource_rsvp |MediaResourceCdpc(2,100,141,56) |MediaTerminationPointControl(2,100,139,5) |2,100,14,24958.2^172.16.101.2^Port 45410
You can find attached the SDL logs (calling number 00634379492, called number : 6840 translated to 8400).
Thank you for your help.
Thomas.

Hello,
We are facing a issue with the TFTP service on our CUCM cluster following the upload of the CallManager multi server SAN certificate upload.
Here is the error message we get from the TFTP service log:
This is not an ERROR message. Multi SAN CallManager certificate has been regenerated on server- [Hostname: ipt-cucm-sub-ren, IP Address 172.16.103.1]. TFTP service is going for self restart. ITL file will be regenerated
As a result, the TFTP service is not stable and restart every 5 minutes and stop after approximately 20 minutes.
We tried to restart the server without improvment.
For information, the CUCM is in mixed mode.
Thank you in advance for your help.
Thomas.

I finally succeded to have the service provider by phone and he told me that his equipment was the one which has to synchronize to my equipment. Not the other way....
I'm sorry, I feel like I wasted your time.

Hello,
I used this documentation to configure my router but I'm not able to enter this command : network-clock input-source priority controller E1 0/1/0 under the controller E1
Here is the show version:
Cisco IOS XE Software, Version 03.17.01.S - Standard Support Release Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.6(1)S1, RELEASE SOFTWARE (fc3)
It's the same thing with the IOS 3.16.
Thank you for your help.
