I have 10 users in an office who uses 7941 phones. we have CME 4.1. The first line is a shared line and all have ext 100. The second line is given separate extension for each individual so that they can make internal calls as well do transfer. Now i enabled voice mail through CUE 3.1 for each user with primary Ext has there second line. now when i press MSG button i hear nothing. Not even a busy tone. Config wise is correct as i have deployed same network WITHOUT shared line in other locations successfully. So is this shared line creating a problem for Voice Mail?
