I have a bcm 400 & installed su 22 service update now I have certain ext's that populated an E "2100E" after the ext. #. These are T7316 sets.I can call outbound via t-1 trunks & make interanal calls from the sets with an E after them,however from other ext's that are in normal operation I cannot call the sets with an E... The bcm populated the ext's with an E to the bottom of the active set list...
