Has anyone encountered an issue with leaving vmail messages on a NEC PBX system when calling from a Cisco CM system. The first few seconds of the vmail message seems to be clipped i.e there is complete silence for a number of seconds and then the message continues as normal i.e the first portion of the message is clipped. We have got VAD disabled and we do not have this issue with other PBX systems.
Or it could be some settings on the PBX vmail systems. Theses PBX vmail systems I believe are independent of the PBX.
Any help will be much appreciated.
