Re: 78xx 7800 7821 " Host not found " Corporate Directory - Page 2

Hello Community,

Following Szenario,

Encrypted Phones SIP 7911, 7931, 7962, 7975 at CUCM 8.6.2 have access long time to the corporate directory and - works fine.

Today I add 7821 SIP Phones and they works works fine, but no access to corporate directory message "host not found" appears. Works also not with non sip secure profile.

The config is the same as the other phones, nothing different. Get the same IP Address Range, same DNS, same TFTP Server etc.........

The Cluster have 3 Servers, First PUB1, SUB1 and SUB2. The Phones are register at SUB1. For me it seems may be there is a problem with the TVS Certification.

But how could I fix this?

Please see attached Trace from the Phone.

I hope the Community could help me to solve the issue.

Really thanks in advance.

Next Strange thing. I figure out what is going on.

- 7821 and 7962 in operation. XML Works for both.

- I deny again 2445 to first SUB.

- Still works well for 7821 and 7962....................long time. Fault not appears.

- Restart both phones. Still Deny 2445.

- 7821 works not, 7962 still works.

Reason: When Networkconnection is deny from Phones to first SUB and the Phones Restart, 7821 no access to xml, 7962 still access to xml.

Bug?

Hi Armin,

Little information is required.

Which IP address is this 10.199.188.176?
What was the server defintion for PUB & SUB i.e. Hostname or IP address?
What is the modification you have done so far for this issue?
From phone setttings what are the TVS servers listed on 7821 ?

Regards,
Nishant Savalia

Hi, I remember me it was a Firewall Port issue.

balabin.va · ‎06-01-2016

Firewall on the SUB? How to fix the problem ?

cco.cisco.account · ‎06-02-2016

No, between phones and CUCM Server.

Hi Nishant, thanks for your support. I am leaving and in Weekend. On Monday morning, I would trace with deny 2445 the OK 7962 Case and the not OK 7821 Case and post the traces here.

The Question is, w/ deny 2445 to the first SUB (TVS) why the 7962 move to the second SUB and it works and why 7821 move not to the sencond SUB and not show Corp. Directory....

Which kind of Traces you need?

Thanks Armin

Thank you for the information. One more input required from your side.

Please share 7821 phone config file. You can get it as below:-

tftp -i get SEP0000DEADBEEF.cnf.xml
