Steps to Reproduce

1. Test connectivity on new CTi link is giving failure message "Pega.ChannelServicesException".
2. Start up the ctilink engine and observe that it is unable to connect to primary and failover hosts. 


Root Cause

Inconsistent ICM versions in use through out the infrastructure. ICM 7x was being used for the SPAIN instance and requires protocol 10, not 14.


Perform the local-change steps:

1. Modify the ctilink engine rule form to use the proper protocol version for ICM 7x.  
2. Change from protocol 14 to 10.
