HI! I have older Cics system Inherited Customer , Not sure what version software but it is old , I was adding M7324 sets ref. Thats what they want. The reception already had a M7324 and a Dss module , i added 7 M7234 telephones so with the reception that is 8 M7324's and a dss module , no voicemail, 8 co trunks . When i go to add the 9th m7324 it boots up display works intercom and no other buttons work , this a existing working digital port which had a m7208 working on it , i tried a another M7324 just in case i had a bad set, did the same ,, so my question is there a limit of M7324 sets allowed on cics , because of extra power from too many M7324,s or is it a software issue or ???? Any help. Thanks again :confused:
