Re: Where to configure CRS to access multiple Call Manager serve
You can add more CallManagers for redundancy after CRS has been installed.
You can add the CallManager redundancy in several places in the AppAdmin CRS administration web pages.
You can add redundancy for the CRS LDAP servers: add the callmanager list, all the names or ip address separates by commas, in 'System'->'LDAP Information'. Add the callmanagers in 'LDAP server host name, IP address, or AD Domain'.
You can add CallManager redundancy too in the JTAPI provider and RmCm provider. You have to do the same process as with the LDAP redundancy. Select 'Subsystems'->'JTAPI'->'JTAPI provider' and populate the 'JTAPI Providers' field with the CallMananger list. Do the same process with the RmCm provider.
You can use the two other CallManagers in your installation. Take care thet the 'CTI Manager' services are ativated and running in those CallManagers.
