I have a new bundled SRST box and I`ve configured ccm-manager fallback etc and the mgcp. Sh ccm-manager shows it is registered and I`ve configured some FXS ports -all good but when I try to create the E1 controller I can not do it- Try to set up the ISDN SWITCH TYPE and I get an error also there is no option of isdn in the conf t ? list . Also how do I check the SRST version to confirm the correct S/W is already installed - sh ccm-manager only shows whether it is registered or not . Should not bundled Router come with all the S/W loaded and if so how do you confirm?
