IVR Voicemail issues

Ahoy,

I am running the latest version of freepbx with asterisk 1.8.23 on:

Distributor ID: Debian
Description: Debian GNU/Linux 6.0.7 (squeeze)
Release: 6.0.7
Codename: squeeze
[email protected]:~# uname -r
2.6.32-5-amd64

I am using callcentric as a provider. I have added the IVR module and have created an IVR with direct dialing enabled that my inbound calls are routed to. On the extension I’m using for testing I have voicemail enabled. If I call the IVR and enter my extension while I have a sip client registered and allow it to ring through to voicemail, or decline the call, then everything works as expected. If I do not have my sip client logged in and I call the IVR and enter my extension I get about a second of the default voicemail greeting before it is interrupted with the beep and recording begins. Below is logs of such a call:

If anyone has any feedback I’d greatly appreciate it. If you need more info just let me know.
