Mitel 3300 MCD connected to Exchange 2010 UM

[simoncroak]

Hi Guys,

I'm just having a play with our Mitel/Exchange environment and I am trying to setup Exchange to be our new Voicemail Server.

I have followed the Mitel "Configure MCD 4.0 UR3 for use with Microsoft Exchange 2010" document and I have followed various how-to's on setting up the exchange side of things, but I have come up against a small issue.

When I setup my mitel desk phone(ext 5508) to call forward no answer to exchange (ext 3200) and then dial my desk phone from an external source (cell phone) I get the "Please leave a message for..." no problem. But when I dial 3200 directly from my desk phone I get sent down the correct ARS route but then I just get "dead air".

The same also happens for the exchange auto attendant, ext 3201. If I connect to it from external source I hear the auto attendant no problem. Calling it from my desk phone directly and i just get "dead air".

I'm guessing it has something to do with the class of service on the SIP trunk. But I don't know all the options well enough to start troubleshooting. Does anyone have any ideas?

My current COS is listed below.

I'm using a Mitel MXe-III 3300 MCD Version 5.0 and Exchange Server 2010 SP2

Thanks in advance.

Not sure its class of service. If you call externally the Exchange server will be receiving a "forwarded from" and then the extension number for the mailbox it should direct the call to. When you call the ARS access code directly to access Exchange none of the "forwarding from" information is sent and I think Exchange doesn't know what to do with your call. Your internal calls to the Exchange would normally be you retrieving your messages i.e entering you passcode to access your voicemail. When you get dead air try dialing your passcode if that doesn't work try another call and on dead air dial your extension number. Your issue might be more about the ARS.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

Hi LoopyLou,

It would appear you are correct! When I dial the auto attendant (ext 3201) and then enter another extension number it forwards me to that extension.

OK so now I know what the issue is. How do I solve it? Whats the best way of dialing the auto attendant via an ARS route and sending the "forwarded from" extension number.

Thanks

Simon

In the case of SIP trunking I am not sure as I haven't done an Exchange VM. We used to put tone markers in the digit mode for the route to the voicemail when we used E&M trunks ( <E> ). Wonder if you need the

COV/ONS/E&M Voice Mail Port set to yes

in the COS for the trunks.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

Hi LoopyLou,

Thanks for that suggestion. I tried changing COV/ONS/E&M to Yes but nothing has changed unfortunately.

Do you (or anyone else) have any other ideas I can try?

Thanks

Simon

 

[LoopyLou]

Did you try putting the tone marker thing I mentioned? You do this in the Digit Mod form for the route you have established to the voicemail. You might need to setup a second and different ARS string for internal callers.

Example 50 is the ARS string to get to the Exchange. ARS string 50 uses route 10. In Route 10 you have digit mod 10. In digit mod 10 you absorb two digits and in the digits to be inserted you put in <E>. This is what we had to do on E&M trunks to a VM. The <E> sends the digits of the calling extension number down the trunks. Again this worked on analog trunks so I am not sure it would work on SIP.

Other then that I would re-read that document on interfacing to exchange especially the MCD side as I think there must be something missing.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

Hi LoopyLou,

Thanks again for your suggestion. I tried <E> as well as <E>#. But I got an "Access Denied".

I also tried <F> but that didn't change anything.

I re-read the document and made sure I had done every step. Which I had. I'm guessing there is something specific about our setup that means it isn't working.

I guess I'm SOL.

Thanks again.

Simon
