Question : Cisco Unity Express to Trigger MWI on overlay DN

Hi All

I'm  trying to setup goup voicemail and i would like the trigger  mwi on the second line . Now the second line is shared as an overlay between 6 phones as shown below. Now I created a General Delivery Mailbox(es) which works fine I can access the voicemail and I subscribed some memebers but when I leave a voicemail none of the subscribed get MWI. How can trigger the on the memebers. With other voicemail system you can do it very easy has anybody done this with unity express.

The reason that I created overlay dns is because I have UC520 which does not support Parallel hunt group Cisco TAC has confirmed.

>>> one of the phones all the rest are configured the same.
ephone  11
 device-security-mode none
 mac-address 0015.6228.9BB6
 ephone-template 2
 type 7940
 button  1:11 2o15,16,17,18


the set up simulates Broadcast hunt group which works great.

 number 4357
 label Main-Number

Answer : Cisco Unity Express to Trigger MWI on overlay DN

Do " debug ccsip messages" while you are leaving the message .
And See what number is dialing from CUE using sip debug for the mwi.
You may get a clue why it is failing.Or post the output of debug
