CME call-forward all configuration is disappearing randomly

[Louis Niel Panganiban]

Hi EXPERTS,

Good day!

We have a center that is using a CME router, and having an issue with this one extension which is 4783. The configuration in this extension is disappearing randomly.  Hope you could help me figure out this issue.

See config below:

ephone-dn  284  dual-line

number 4783 secondary XXXXXXXXXX

label 4783

description X

name X

call-forward all XXXXXXXXXXX

call-forward max-length 12

hold-alert 30 originator

night-service bell

IOS ver:

Cisco IOS Software, 3800 Software (C3845-ADVIPSERVICESK9-M), Version 12.4(4)XC6,                                                                               RELEASE SOFTWARE (fc2)

CME ver:

Version 4.0(3)

Cisco Unified CallManager Express

Thank you very much.

@ Sir Paolo: Is it advisable to upgrade the IOS to XC7? Will it affect the license and or the CME version? Thank you.

Hi,

when upgrade the IOS it will change the version of CME. kindly find the below link for compatability matrix

make sure that the new IOS meet your current memory and flash.

regarding the new CME version, make sure it is compatabile with Cisco unity express version if you have one
