FXS port/MGCP debug

Hey Everyone,

Can someone provide some insight into troubleshooting a MGCP FXS port that is giving a cause code "Cause i = 0x8091 - User busy". I have tried resetting the gateway and doing a no mgcp, mgcp.

'show voice port summary'

show voice call summary

debug vpm signal

debug voip ccapi inout

debug mgcp packet

Find out if the packets from CUCM are getting to the gateway. If not, CUCM thinks it's busy. If the packets get to the gateway, the gateway thinks it's busy.
