fxo outgoing calls getting fast busy (mgcp)

Hello,

I must be doing something wrong, but can't figure out what.

There are 4 fxo ports configured. Everything is working fine but after quite some time, all outbound calls fail. Incoming calls are working fine but users are not able to make the outgoing calls. Already tried disconnecting from the FXO and use an analogue (POTS) phone and we can make outgoing calls. Already tried to reseat all the cables connected to the ports, also reseated the module itself. Also done reloading the router but still no outgoing calls. gateway and all the ports shows as registered on cucm.

I have attached the show run, vpm signal and voip ccapi inout debugs. Can you please help?
