Having a strange issue, no idea why. I've installed CUCM 6 and everything appears fine with that. I went through the Cisco Guide for Unity 7 SCCP integration with CUCM 6.x and that all appears fine. I can connect to Unity Connections fine, the Voicemail buttons on the IP Phones work fine as well. I've imported the CUCM users into Unity Connections as well. I have a partition setup on CUCM "RCSIPP" contained in the CSS "RCS_CSS". The Unity VMPilot partition is also contained in that CSS. I created a DN "1000" and set it up to forward all calls to VoiceMail. I assigned that DN in Unity as the extension for the System Call Handler "Opening Greeting". When I dial in from the PSTN or within the network using 1000, the Opening Greeting call handler picks up. When I dial an extension for a user configured in Unity, I hear the "Please wait while we transfer you to that extension" but then the call goes directly to voicemail. For troubleshooting purposes I even disabled all voicemail forwarding on the user.
When I place the user's DN into the <none> partition in CUCM, then the Unity Connections Call Handler forwards perfectly to the user's extensionas it ought to. I have gone through seemingly every setting that seems to have an effect and yet nothing works. The only temporary workaround I have found is to place all CUCM DN's into the <none> partition. I know I have had this working before, I thought I had setup everything correct this time as well but am apperently missing something? Any help with this issue is GREATLY appreciated. Most likely it is something stupid I am overlooking but this is very very vexing. Thanks in advance for any assistance.
I know you provided partition and CSS assignments in your post but it isn't clear to me what partitions your phone DNs are in and what CSS is assigned to your voicemail ports. Your voicemail ports will need to have a CSS assigned which includes the directory numbers for the lines assigned to your IP phones.
You can also use Dialed Number Analysis (DNA) to confirm that you can reach the IP phones partition from the CSS assigned to voicemail ports. You could also configure one phone to use the same CSS as the voicemail ports (double check that line CSS configs match as well). Then see if you can call other extensions.
You can also check restriction tables. I believe the default config should be adequate, but that depends on what your extension range is. For instance, a leading "9" on your extension range may require you to tweak the restriction tables.
Finally, check what the "transfer extension" is on your test voicemail users just to be sure. I suspect you have already done this and you have a CSS/partition issue.
