I have a Nortel 4.0 CallPilot delivering messages to a Cisco UCM 7.0 IP phone. The Nortel and Cisco have a QSig PRI setup between the two. Occasionally users are complaining that they have voicemail message in mailbox but no messaage indication or the message in the mailbox was left several days ago by the time stamp but just received in the mailbox today. Has anyone experienced this and resolved?


 
Not very familiar with call pilot but could it be this scenario:
Day1- User has MWI and two new messages. Checks only one and not the second. MWI goes off.
Day3- User checks their vm and finds a new message from 2 days ago, the one that did not get checked earlier that week.

Not sure if call pilot will leave the MWI on or off after messages are checked partially, but I would bet it turns it off. Seen this happen again and again with users.

If you have eliminated that option, you need to ts the call pilot and see why it's sending delayed messages or not lamping the phones. Could it be the QSIG is getting congested and ports are not available? Is the QSIG not set up properly? (doubtful or MWI wouldnt work at all)
