Hi, According to the wiki, we need to have both callwaiting=yes and callwaitingcallerid=yes , and that's what I have in zapata.conf. I can hear the call waiting alert tone when a 2nd call comes in during an established call, and I can switch between the calls without problems. However, CallerID on the 2nd call does not show up with the call waithing alert tones. Am I missing something? Can anyone help? Thank you in advance. Andy
