To verify MGCP-controlled endpoints configured for SS7 and ISDN PRI, use the show mgcp endpoint command in privileged EXEC mode.

Note Note: The show mgcp endpoint command does not show configured endpoints for CAS, including FGD-OS.

The following example shows MGCP endpoints for a NAS package:

controller T3 9/0
 framing m23
 cablelength 224
 t1 1-8 controller
!
controller T1 9/0:1
 framing esf
 ds0-group 0 timeslots 1-24 type e&m-fgb mf dnis
!
controller T1 9/0:2
 framing esf
 ds0-group 0 timeslots 1-24 type e&m-fgb dtmf dnis
!
controller T1 9/0:3
 framing esf
 ds0-group 0 timeslots 1-24 type e&m-immediate-start
!
controller T1 9/0:4
 framing esf
 ds0-group 0 timeslots 1-24 type e&m-fgb
!
controller T1 9/0:5
 framing esf
 pri-group timeslots 1-24 service mgcp
!
controller T1 9/0:6
 framing esf
 ds0-group 0 timeslots 1-24 type none service mgcp
!
controller T1 9/0:7
 framing esf
 extsig mgcp
 guard-timer 10 on-expiry  reject 
 pri-group timeslots 1-24 service mgcp
!
controller T1 9/0:8
 framing esf
 extsig mgcp
 guard-timer 10 on-expiry  reject 
 ds0-group 0 timeslots 1-24 type none service mgcp
!


The following output shows available varieties of CAS:

  • 9/0:5-ISDN backhauling
  • 9/0:6-SS7
  • 9/0:7-ISDN backhauling with NAS package
  • 9/0:8-SS7 with NAS package
