Change CUCM IP address then Unity no longer works

[stivermr1]

I am running CUCM 10.5.1.10000-7 and Unity 10.5.1.10000-7.

I have a single CUCM and Unity.

I change the IP address on the CUCM, updated DNS, and the TFTP setting. Everything on the CUCM works fine with the new IP address except for when I try to call the voicemail pilot number I get a busy signal. I changed the CUCM back to the original IP address then everything works normal again. I have tried stopping/starting services, as well as rebooting when I changed the IP address. I have to be able to change the IP address when I move it to production since I have it on a test VLAN right now.

In Unity Connections, Under Telephony Integrations --> Port Group --> Click on Group, then edit --> Servers

Make sure the changes are reflected here to the CUCM servers. If you are using DNS, make sure Unity has updated its DNS settings. I would recommend using IP addresses if you are using host names.

Thanks a bunch. I forgot about the Edit menu. I have been digging around for hours trying to figure out what is going on. I knew it was on the Unity side since when I changed the CUCM IP address back it worked. I was trying to find a command that listed the configuration, so I could find out where the CUCM was linked in.

Hello

1-After you change the IP address on CUCM , did you change it on CUC?.On CUC " CUC - telephony integration- Phone system" phone system -edit should update to the new IP address .On CUC " CUC - telephony integration- Port group" phone system change the IP address to the new IP address of CUCM .Port group " need reset "no"" .

2-After you change the IP address , you have to check the voice mail ports on CUCM under CUCM  "CUCM - advanced features-voice mail ports" , become registered or not .I hope to check all of these information.

Hello

1- Did u get your  problem  after you add the subscriber IP address to CUC ?.

2-Did you list Sub and Pub  on your phone system "Edit-  AXl " and port group edit "Servers"?.Are u sure that you add correct IPs?.On your CUCM - VM ports , the VM port registered to the IP of subscriber or publisher ?. Can you do reset from CUCM for VM ports , please?.Check also the hunt pilot number and voice mail pilot ?.

3-Finally if you are sure from your configuration ,yup you can do restart for CUC , ssh CUC - type username and password , then type  utils system restart .
