IP Office centralised voicemail

[PaulCarter]

i have 2 IP500 systems linked via SCN (1 is 5.0 and the other is 4.2 software)
They have centralised voicemail which has worked fine but now all of a sudden the secondary site doesn't get notification of their voicemail messages. They can use voicemail fine by dialing it and they are getting their voicemail messages just not notifications.
Any ideas?
Thanks

try to stop and restart the voicemail pro service and retest

sorry I should have mentioned that I have restarted the phone system (the secondary site with the fault) and also rebooted the VM Pro server

Then why not upgrade the 2nd site to a 5.0 to match
