Time-slot configuration changes after reload

Unanswered Question
Dec 4th, 2007

Hi there,

I have a Cisco 2811 configured as a voice gateway. The IOS version:

c2800nm-spservicesk9-mz.124-11.T2.bin

The issue is that after every reload, the config for the E1's timeslots will change from 1-5 to 1-31.

E1 configuration

------------------

controller E1 0/0/0

pri-group timeslots 1-5,16 service mgcp

Appreciate if anyone could assist as to why it is happening

**The config file is attached**

The reason is that when the gateway reloads the following command 'ccm-manager config' downloads the configuration from CallManager, and consequently will reconfigure the pri-group with all timeslots. This is normal behaviour.

Therefore in order to ensure that this does not re-occur simply remove the command 'no ccm-manager config' after you have reconfigured the pri-group.

Incidentally after reconfiguring the pri-group verify that your xcode/cfb resources are up. You may find that as the pri-group was using 30 Channels you would have had insufficent DSPs for your DSPFARM. In this is the case, simply initiate a 'shut' and then a 'no shut' on the profile.

Hope this helps.

Regards

Allan.
