Transfer direct to VM

Recommended Posts

We have a somewhat unique situation in which some options on our auto attendant should transfer a caller directly to a user's voicemail box rather than ringing their extension. When using the internal voicemail on pbxnsip, all we had to do was have those options transfer to 8xxxx where xxxx represents the user's extension. When using Exchange integration, the wiki states to ensure that the direct to voicemail prefix is removed (I tried putting it back in and using it just to see if it would work. It didn't.). How can I accomplish a direct transfer to a user's mailbox from an auto attendant when the mailbox is hosted on Exchange UM?

 

Transferring to 4xxxx doesn't work (where the external voicemail system is defined as 4$u, and 4* is setup on the dialplan to go through the exchange UM trunk), as it seems that that triggers the subscriber access greeting rather than the mailbox for the user. The only way I've found to make it work is rather a kludge. It involves creating a second extension for each of the users in question, associating that extension number as an additional EUM address on the user's Exchange account, and setting the extension to transfer to voicemail after one second in pbxnsip. Then, when I want to transfer directly to someone's voicemail from an auto attendant, rather than to their usual extension, I transfer the caller to this new extension. While this works, it requires an additional extension license to be used for each user that I want to implement direct to voicemail dialing for. Am I missing something obvious, and is there another way around this? Thanks in advance.

I guess we should just investigate why the auto attendant does not send the call to the Exchange...

Is there anything I can provide that would help the investigation? Thanks again.

Hi Enercia, :(

 

one solution might be the Exchange UM autoattentend! As you can see in the picture, there is an option called "Allow callers to send voicemessages", which is off by default ExUM AA setup:

You can find more detailed info @ managing-unified-messaging-auto-attendant part 1- 4 !!!

 

Maybe you will be suprised about all options the ExUM AA can offer by default and how you can extend it!

 

regards,

 

Jan

The Exchange AA doesn't give me quite the functionality I need (e.g. Press 1 to leave a message for.....). I stumbled on a solution tonight, though. It seems the OCS 2007 R2 response group service does what I need. I've got that setup and working perfectly. Thanks.

I have the exactly same Problem: Transferring Calls directly to VM (Exchange) costs me a 2nd licence for each user. All the following attempts were in vain:

- Creating ONE Extension for all Users, but adding ALL VM-Numbers in the Field Extension Number, separated by space

Didn't work: The Call is always forwarded to the VM of the FIRST Extension Number only

- Creating Hunt, Group, Auto Attendand, Agent Group with forwarding to Exchange (Dial plan set to use the Exchange trunk)

 

It seem silly to attach a 3CX as an sub-pbx in order to do not waste Extension-Licences...

 

So I think about another method of resolution:

 

Is it possible to just insert the follow SIP-Command in the Trunk-Setup in some way (and create as much trunks as we need Exchange UM-Users)?

Diversion: <tel:12345>;reason=no-answer;screen=no;privacy=off (where 12345 is the UM-Mailbox-Number)

(I've heard people working with Asterisk can do this without any problems in their pbx)

I've read the above mentioned description, but didn't found a solution to setup the auto-Attendand in such a way the call is answered, than nothing or just a beep is played and then a fixed UM-Voicemailbox is called without any other interconnected messages or user intervention by pressing any buttons.

 

I need to setup as much auto-attendands as I need UM-Voicemailboxes for direct transfer.

 

Any idea?
