ESI seems to have a known issue of not being able to show the CID of a second call ringing in to the receptionist if she is already on a call. Comm Server or S class both have this issue. I have tried CO lines to dept 290 with 3 members and CW enabled on dept and on the three phones. I have also tried CO lines to INFO box 300 with 1/2 sec silence recording then CF Bsy/NA to 290. That almost worked but the 2nd CO light went solid before it could be answered.
Any other ideas? What am I missing?
