Calls to extensions not ringing

[LFehr]

I have an IP Office 500 with VM Pro with about 70 IP phones, 48 VMC's and 30 VM channels.
When a call is placed to the main number from an outside line and they dial the 4 digit extension, sometimes it just gives dead air for 30 seconds and then rings the users extension. Other times it never rings the extension. And most of the time, it just rings through right away just fine.
The network was just replaced with brand new Cisco 3560 switches configured for VLAN's and QoS. The call quality has greatly improved since doing this, but now the new problem above is showing up.

Any ideas what could be causing that?

Thanks,
LF

There was an issue in 4.0.7 that, when using an unsupervised transfer within VMPro, the phone wouldn't ring but rather the caller would go directly to voicemail. Fixed in 4.0.10. Assisted transfer worked every time in 4.0.7

Thanks,
We'll update the version and hopefully it will fix it.
