Unable to get phones registered in CUCM

[aaron-saz]

I’m running CUCM 10.5 in my lab and I have 3 phones I’m testing with 7960, 7940, also tried 9971. Neither of the 3 register (registered: unknown) in call manager, but I can change line numbers and display settings in CUCM, and see the updates on each of the phones.

On both the 7900's I can pick up the hand set and initially get a dial-tone, but when the phrase “your current options” flashes (constant flashing across bottom of display panel) the dial tone stops, it’s like the phone is being reset. The 9971 just says Unregistered..

I have a couple IP communicator phones that both register, and can call each other…

SIP trunk in CUCM shows as active and functional. Parts of the VG and SW config that relate to the VoIP are listed below.

- VG: 2801

c2801-ipvoice_ivs-mz.150-1.M10.bin

- Switch: 3750

c3750-ipservicesk9-mz.122-25.SEC2.bin

I have another thread at the below link..

Any advice would be greatly appreciated.

What is the Firmware running on these phones ? did you check the compatibility matrix with CUCM 10.5.

Also can you please take a packet capture by spanning a switch port for one of the phone hooked up on switch or enable the PC port on phone and connect laptop or PC back to phone for taking packet capture.

[aaron-saz]

Firmware info below. I guess I assumed they would work with a 10.5.. I’ve had them tested on a 11.xx CUCM in the past.  

From the Phone:

7960: P0S3-8-12-00
7940: P0S3-8-12-00
9931: sip9971.9-4-2-13

[Nadeem Ahmed]

Can you perform one thing before get into the packet capture things..

Delete the CTL and ITL from phones  if phone status still unknown and you are getting dial-tone then run this command from CLI : show risdb query phone 

if phones are showing registered while running this command  please restart the below service on CUCM

"Restart the Cisco RIS Data Collector on all the servers"

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/uc_system/unified/communications/system/versions/IPTMtrix.html

[aaron-saz]

I've reset the phones a couple times - does that delete the CTL and ITL from the phone?

I don't show a CTL File under settings -> security configuration.  Attached is a screenshot of the output from show risdb query phone

[Nadeem Ahmed]

reset phone do not delete the CTL and ITL files from the phones.

#setting>Security Configuration>Trust List>CTL (Select and delete by unlocking phone by pressing **#) if there is no CTL file move on the ITL if there is

#setting>Security Configuration>Trust List>ITL (select and unlock phone erase )

[aaron-saz]

I reset the phone and did not delete config file.  I do not see CTL or ITL files on the phone.  Below is the the navigation path to the CTL Location and what is listed

Settings -> Security Configuration -> 1SetCfgEncryptionKey

[Nadeem Ahmed]

are you not able to see TRUST LIST

setting>Security Configuration>Trust List> ITL FILE.

Can you please confirm what is the state of the phone its showing on the phone screen. can you please pull CCM trace while resetting one of the phone or take pcap as suggested earlier to identified what exactly its causing this issue.

Please check attached file to validated the ITL file on the phone

[aaron-saz]

Please see the attached pic and log (rename 2016-08-16--0927.jpg to 2016-08-16--0927.cap). Below is the tcpdump command I ran for reference.

Hi Aaron,

Are you running Call Manager Cluster With PUB and SUB in the Lab setup ?

Regards

Inderpsi

[aaron-saz]

This is just PUB config.   No SUB

[aaron-saz]

Well embarrassingly enough, I just noticed that the one and only external phone I can get working in my Lab is registered as SCCP. Not sure how that happened as I was pretty certain I was loading all phones as SIP.. And the CIPC phones are registered/working as SIP… But never the less……

I did a trace on 7960 phone trying to register as SIP… I have highlights below and the trace attached..   Please rename 2016-08-18--0817_7960_SIP_Logon_Trace.cap.jpg to 2016-08-18--0817_7960_SIP_Logon_Trace.cap.pcapng

Anybody have some more thoughts on my issues?

Highlights:
CUCM: 192.168.10.5
7960: 192.168.20.31

Just a bump to see if there were anymore ideas out there?

thanx

[aaron-saz]

Resolved:

Some of the phones are SCCP only and some of my phones are SIP only..  I am able to get them connected and working using one of the protocols, but unable to get them working if I try to switch protocols for example SCCP to SIP.

[aaron-saz]

UPDATE:

I am working with 3 different model phones 7960, 7940, 9971 (Added my bosses phone for testing) and CIPC running on 2 different physical devices.  All 3 of the physical phones work as expected on our company CUCM cluster.

In my Lab:

Both CIPC's and the 7940 are registered and can call each other.  The only change was Plugging in the 7940 to our Cluster.  The 7960 and 9971 were also plugged in to company Cluster, but still not working in lab.  

9971:  Still not registering - I replaced cables and swithports with the working 7940 - still no luck

7960:  Still flashing "your current options" across the bottom and not registering.

The regards to the working 7940:

 - Does not have a CTL file installed

 - Security Mode is set to Non Secure.  

 - Trust list is empty

And I can get to the web access page on the phone.  (Clicking on the phone IP in CUCM)
