Configuring Unity Connection in a HA cluster

Yesterday got an oppurtunity to work on implemeting Unity connection in HA using SIP.
The steps are staright forward :

In CUCM

1. Create a two SIP trunk to Unity Connection
2. Create a Route group
3. Select the two SIP trunk in the route group
4. Create a Route List and add the route group to Route list
5. Create a specific Route pattern  for voice mail will be same as voice mil  pilot and select the voice mail route list in the route pattern
6. Create a voice mail pilot same as the route pattern
7. Create a voice mail profile

Unity Connection config

Note : We can only  create cluster of two server for unity connection and each server license will be based on its own mac address( Not same as CUCM licenseing )

1. Create Phone System
2. Create a Port group and select SIP as a protocol
3. Add a port group, remember to add different port group to different server
4.  Add the CUCM server IP address in the SIP IP Address field which you can get from the Edit tab


Now check the integration by dialing the voice mail number..It should work.. :-)
