Is there anyway to change the behavior of the auto answer configuration for each line? Clearly, it's either on or it's off. But the customer has an old key system that auto answers internal calls, but when external PSTN calls come in, the phone rings 4 times, then to VM. I have played around in MGCP with the ONNET OFFNET setting and that did not change anything.
Service Parameter? Or is this not possible in CUCM
