CUE/CME MWI calling phone's DN

[michael_luo]

I was trying to set up MWI on CUE/CME integration.  However, whenever I left a message, CUE will call the phone's DN for two rings but not lighting up the LED.

Here's the config on CME

ephone-dn 8

number 1998....

mwi on

ephone-dn 9

number 1999....

mwi off

On CUE, SIP gateway is pointing to CME's IP.  MWI on/off are 1998 / 1999.

Did I miss anything?  Why CUE just calls the phone but not lighting up the MWI LED?

Thanks!

Hi Michael,

Did you try the steps in this good doc

Troubleshooting Unity Express Message Waiting Indication (MWI) Problems

Hi Rob,

Thanks for the reply.  Yes, I reviewed the link you sent before posting.  But I couldn't spot anything significant from the trace.

Attached is the "debug ccsip message" output.

Thanks!

Thanks again!

From my understanding, there are three different options for CUE to deliver MWI:

• Subscribe - Notify
• Unsolicited Notify
• Outcalling

Since all my CME phones are SCCP, I'd like to test "Outcalling".  Do I still have to configure the following?

sip-ua
 mwi-server ipv4:10.168.2.253 expires 3600 port 5060 transport udp
!
ephone-dn  1 
 mwi sip

I thought the above are only required for "Notify" methods.

Here's another link I found regarding those three options:

Hello Michael,

A few things you can check:

1. Have you created an inbound voip dial-peer for the MWI numbers? and set the codec to G711ulaw, for example:

dial-peer voice 1999 voip
incoming called 199[89]....

session protocol sipv2
codec g711u

dtmf-relay sip-notify

no vad

2. Configure this on your sip-ua

sip-ua
  mwi-server ipv4: expires 3600 port 5060 transport udp

3. under voice service voip, do not bind SIP control/media to loopback or else MWI will not work

4. for the MWI DNs, I suggest you put no-reg at the end, example:

ephone-dn 8

number 1998.... no-reg

mwi on

5. finally after all the configuration changes, go to the CUE CLI and run 'mwi refresh all'

Victor Dang.

Thanks for the response.  It turned out to be a translation rule that was affecting the MWI call.
