When you create the MGCP port in CUCM and it asks you to pick POTS, Loop Start, or Ground Start, choose POTS. Then add the 1001 DN to it.
Edit: Actually, it seems the problem is with an FXO, not FXS port. Disregard.

hi
i didn't find POTS on fxo port , juste loop start or ground
when i choose ground the call still desconnect after 4 seconds

i was unable to understand what you meant by " the call is answred even the ip phone not answered yet". so just looked in logs for call disconnection during the call.
looking at the call legs 47 , it seems disconnection is happening from incoming leg from cucm.
