Re: [cisco-voip] what's the NC model of phones?

2019-09-17 Thread Chester Rieman
CP-8845-NC-K9= is called 
Cisco UC Phone 8845

CP-8845-K9= is called 
Cisco IP Phone 8845 

I have no idea what the diff is between an IP phone and a UC phone

Re: [cisco-voip] CUCM SU release cycle

2019-08-21 Thread Chester Rieman
Hi Lelio,
 Checked that here:
Compatibility:
https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-communications-manager.html
 
<https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-communications-manager.html>



I Believe a large part of it was to implement workaround for specter/meltdown

Banner message when upgrading:

Warning: The following phone models are deprecated and no longer supported:
 
12 S, 12 SP, 12 SP+
30 SP+, 30 VIP
7902, 7905, 7910 (including 7910 SW)
7912, 7920, 7921
7935, 7970, 7971
 
After you upgrade and switch over, these unsupported phone models can no longer 
register with Cisco Unified Communications Manager. Please power down and 
remove these phones so they do not continue registration attempts. Keeping 
these phones on your network creates unnecessary network traffic and load on 
the UCM service.
 
This is a Refresh Upgrade. Refresh Upgrades require an extended service outage 
and multiple reboots. Please refer to the Software Upgrades section of the 
Cisco Unified Communication Operating System Administration Guide for more 
information.
 
If there exists any weak ciphers (like 1DES,null_encryption, blowfish448, 
rijndael, md5 ) in IPSEC policies then they will be converted, 1DES as 
encryption cipher will be converted to AES128 ,
MD5 as hash will be converted to SHA256 and null_encryption,blowfish448, 
rijndael  as ESP to AES128.
 
In order to use Certificate-based authentication with IPsec both sides of the 
connection must use certificates signed by the same root CA in the trust chain. 
Self-signed IPsec certificates are
no longer supported and IPSec connections using self-signed certificates will 
fail.

Just to Chime in here….

From what I have seen upgrading in the lab upgrading to 12.5.1.11900-x 
(12.5(1)SU1) from almost anything (even from 12.5.1.1-22) should be 
considered a major upgrade,
Similar to 8.6 where CUCM went to SELINUX with a new OS install.(especially 
true when coming from 11.x since that OS is still redhat)

https://www.ciscolive.com/c/dam/r/ciscolive/us/docs/2018/pdf/BRKUCC-2011.pdf 


VMware shows CentOS7 is supported on ESXi 6.0.0 but Cisco says you need 6.5/6.7 
(which is true)

11.x is RHEL6, 12.0 is CentOS6, 12.5 is CentOS7 and may involve an ESXi upgrade 
prior to upgrading.

Bottom line, upgrade ESXi to 6.5/6.7 prior to attempting UCOS upgrade to 
12.5(1)SU1 and you cannot do a fresh install of 12.5SU1 but you can upgrade 
from  base 12.5.1:

Re: [cisco-voip] CUCM 12.5 CCMAdmin login error

2019-04-03 Thread Chester Rieman
There were a bunch of phones(79xx) deployed with bad spring in the hookswitch:
CSCto78441

Symptom:
7962 phones are going off hook and then on hook 400 milliseconds later, which 
prevents the user from answering the call properly.  This behavior can be seen 
in the SDI traces:

11:33:42.540 |StationInit: (030) OffHook.|1,100,49,1.584290

and then back on hook roughly 400 milliseconds later:

11:33:42.981 |StationInit: (030) OnHook.|1,100,49,1.584297

Conditions:
This can occur on 7942 or 7962, and is more likely to occur when the phone is 
sitting at a steep angle and especially with a sidecar attached.

Workaround:
1.  Invert the wall mount tab to be in wall mount mode.

2.  Reduce the angle at which the phone is sitting by two notches.  This may 
not be possible if a sidecar is mounted.

3.  Do not use a handset, use only a headset.

4.  Open a case with Cisco Customer Service or Cisco Technical support to have 
the affected handsets replaced.
