The customer has a portable phone in front of the old 616. I'm going to install a cics with 7.1 sw. They have caller id on the portable, they want to keep the portable for the emergency phones, will this affect the caller id to the other phones, or should I connect the portable to the emergency phone connection. They like to see all the caller id from telco like name/number all together. if I connect it to the emergency coonection will they lose all caller id features, or will they get name or just number if connected to system. Thanks
