Hi, send show diag. Most likely you do not have dsp resource and need to add the in the form of PVDM-256-XX modules.
Hope this helps, please rate post if it does!

Do a SH DIAG and check the type of DSP module you have installed in the router. I suspect you don't have enough DSP resources for the 4 B channels on the 2 port BRI and the 2 port FXO ports.
Paste the SH DIAG output here so we can confirm.

Hi all.
Seems you guys replied at the same time and made more sense to me as well.
Cheers ;-)
Thot.

So now a race to give you the final answer :-)
You have a PVDM-256K-4= DSP module , which will only support 4 channels, which would be the 4 B channels of the BRI card, or the VIC-2FXO, but not both at the same time.
You will need a PVDM-256K-8= at the very least for this to work.
