I've tried, but it just show the calls that use SIP calls  :

All calls that display star and nothing after are calls made from MGCP

Then you need to run a "debug isdn q931" and be sure you can see the Calling and called number from the MGCP gateway.

This appers in the show isdn status

rtVg00#sh isdn status
Global ISDN Switchtype = primary-net5

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply

ISDN Serial0/2/1:15 interface
        dsl 0, interface ISDN Switchtype = primary-net5
        L2 Protocol = Q.921 0x0000  L3 Protocol(s) = CCM MANAGER 0x0003
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
