10.10.11.8 to control gateway 10.10.10.116:
FWSM/contexta(config)# mgcp call-agent 10.10.11.5 101

FWSM/contexta(config)# mgcp call-agent 10.10.11.7 102
FWSM/contexta(config)# mgcp call-agent 10.10.11.8 102
FWSM/contexta(config)# mgcp command-queue 150
FWSM/contexta(config)# mgcp gateway 10.10.10.115 101
FWSM/contexta(config)# mgcp gateway 10.10.10.116 102
