looks okay...  are you sure this is the right gateway?

 

what version of CUCM do you have and what version of IOS are you running on the VG?  did this ever work?

hello ,

 

i asked to my team regarding same, and they there is no PRI @ DC,HO and all branches. How Shoould i sort out this. We are getting multiple alerts in day.

 

Any Solution for this.

 

Still, i am getting same alerts.

 

MGCP DChannel is out-of-service
D-Channel-Out-Of-Service status in gateway device(s): S0/SU0/DS1-0@voicegateway

 

 

hi!

 

Voicegateway is the router name as it is presented to call manager. if you go into CUCM and go to device --> gateway and looking for a device called  voicegateway you should be able to do a show endpoints to confirm the routers IP address.  Have your staff log into that router and do the command above.  Also, do a show log and see what the router is saying for the time period CUCM is generating the alert.  It's possible the PRI is bouncing and by the time your staff gets into the router..  the PRI is backup again.

Do you have any reports of dropped calls?

 

Thanks!
