Replacing VG224 in Cisco Unified Call Manager (CUCM)

Yahya Lababidi

Level 1

Hi,

I'm getting ready to replace some of the Virtual Gateways (VG224) at one of my sites and have a few concerns:

  1. Will copying the configs from the old VG224 to the new one be sufficient?
  2. What needs to be done on the Cisco Unified Call Manager (CUCM) to complete the VG224 replacement?
  3. Will I need to change any configs in the Cisco Unified Call Manager if I change the IP address of the VG224 (migrating the VG224 to the new voice VLAN)?

Thanks,

Yahya,

Hope you doing well...

V is standing for VOICE, not virtual. So vg224 will be voice gateway224. The answers for your quastion will be...

1- Yes, it's sufficient.

2- CUCM administration page > device > gateway > find. Then select your gateway, change mac address ( 10 digits ) of the old device with the new one.

3- with using sccp protocol, CUCM don't care about ip address, it's only care about mac address. So the answer will be, NO .

hope that could help

Hi,

First you have to tell us in which protocol did your vg224 works on ??

I use SCCP for my protocol.  

Thanks for your anticipated assistance.

Hi, and thanks for your reply.

Upon replacing the VG224 none of the analog phones registered on the CUCM.  I ran sh sccp on the new VG224 and received "SCCP application services(dspfarm profiles) are not enabled or haven't associated to SCCP CCM group".  I tried to reset the SCCP (no sccp/sccp) and that didn't seem to fix the issue.

I copied the original configuration exactly as is to the new VG224, only thing I changed was the passwords, would that be the reason?

Thanks again for your help.

Hi,

The answer to your question number (2), did you worked with it ?

Hi Saif,

Yes, I did change the MAC address in the CUCM to the new VG224.

Thanks for your kind support.

Yahya,

Cisco vg224 have 2 fastethernet port on its back, did you connect the same interface as the old one ? If yes, then please upload the running configuration of the device here. It will be easier to troubleshoot.

Regards

Yes, used same port (Fa0/0) as the old VG224 with same configs and IP addresses.  I know that network and vlan routing is not the issue here as I can ping all sides from the new VG224 just fine and the old VG224 works fine when I put it back in place.

See current configuration below, and thanks again for your help.

Hi,

Hi Saif,

Enabling stcapp totally fixed the issue and the new VG224 is working now.

Thank you so much for your help.

Regards,

Hey, that fixed my VG204 not associating with CM.  Thank you!!

 

Enables SCCP
VG204(config)#stcapp ccm-group 1
VG204(config)#stcapp

 

Bam!

Thank you Saif. I spent endless hours troubleshooting an analog phone registration failure and all I had to do was conf t -> stcapp.   So Simple. THANK YOU.
