Hi Carl,
You will need to reconfigure the pri-group command near the top of the configuration. You will see a line similar to this below:
controller e1 1/0
You will need to look at the line shortly after that which should start with:
pri-group timeslots 1-31
It may have some other options after the 1-31 command which you will need to note before changing this. You can then go ahead and enter the new command with the new timeslots used (1-8).
Hope this helps
Michael

hi there, i have done this, for some reason it says
pri-group timeslots 1-8,16 ,why does it say 16 ?

is there anyway of checking to make sure its attempting to make an outgoing call ?

Hi Carl,
There is a debug isdn q931 command which will show details of outgoing calls using the PRI.

Hi Carl,
I would say it says only 8 or 16 is because you can only order PRIs in groups of 8, or the full E1 channel.

I have done a debug isdn q931 and it doesnt do anything, if I ping a remote router, nothing happens at all, is there anything i can check to see if the isdn lines are up ?

It say's 16 as this is the D-channel for signalling
Usae the show ISDN ser command which will show the current status of the channels on the PRI
