Actually, the audible message waiting indication (ie. "stutter" dial-tone) is a function of the CUCM.  You can modify it on the Device level as shown here:

In the above example, "stutter mwi" is enabled.  This can also be modified under the service parameters for the Cisco CallManager service.

I believe this is a function of the call control (PBX) as well as the device terminating the phones (VG224, for example). Are you using Communications Manager or another PBX? What type of gateway?

Hope this helps.

If you are using a PIMG or TIMG, there are settings you need pay special attention to.  Also, you will need the latest firmware and ES fix for Unity CUC 7.1.3.   I had a CUC and PIMG last month that I went round and round on.  The voicemails when recording would be choppy.

What is your integration?

CUC 7.1.3(B) integrated with CUCM 7.1.3(B); I thought that maybe stutter was a built in option with CUC or CUCM but it sounds like it is not?

Thank you...

Thank you, I tried the service param and tested it ona phone with mwi light already but it didn't work so I put it back to off, maybe I just needed to wait until a new messege has been recieved for that to update.  Again Thank you thats the answer I was looking for....

Actually, I did the same thing before posting my reply and I though that the setting didn't work.  However, I discovered that the audio feedback offered by CUCM isn't exactly a "stutter" dial tone like you may have from Centrex or your home phone.  When you go off hook, wait a little over one second to hear the "break" in dial tone.  The dial tone will repeat the break three times before returning to a steady dial tone.

Hey TCAT,

Sorry to interrupt this thread......

We just ordered a couple of PIMG units to use with our

Unity Connection deployment. I'm curious to know about these

ES's and any other info you could share with your dumb@!# friend

here. This is our first time to use the PIMG integration.

Cheers

Wow!  I get to answer a Rob Huff-ster question?!!  I feel honored today.. ha.

Here is the ES info TAC gave me.  

UCSInstall_UCOS_ES_7.1.3.21006-1     You have to request it.

Related to BUG: 
CSCtb71551 "UC with PIMG fails Keep Alive and erroneously places port out of service".

Ports kepts dying out on the PIMG for no reason.


Then on the PIMG side... there seems to be a memory leak with
pre-6.0 SU3.1.   If you can find or request anything later
that will help the PIMG.

Also pay special attention to the setup guide.  There are on/off triggers for the VOD that was having an issue.  I replaced one
and did an export/import of the config and when it came back apparently it did reset those triggers. which caused my
choppy voice. (only on recording?!)

This is the exact version I had the PIMG Mitel and it finally fixed everything (with the help of the ES for CUC.

6.0.SU3.1.003_B002_74899.1| |MON OCT 26 18:47:46 2009|

If Cisco does not have it on the CCO, email diaglogic and they will get it to you no problem.  The Diaglogic forums helped as well.


Otherwise for the last 2 months, the PIMGs have been good.  Right now, we are in the middle of a migration and all
users are on the Mitel, but using the PIMGs with CUC.   I will then start sliding the Mitel users to Cisco phones in phases. (basically,
move voicemail first, then the phones... its easier on everyone!)

cheers! and holler if you have questions of course!

Great thread here. The only thing I would add here is for general PIMG installations. One of the things I see missed that also helps the overall health of said integration is to make sure you look at the first step in setting up the PIMG in the integration guide. It says to make sure you use the latest firmware available on CISCO's site. Sometime PIMG are sent with firmware that has not been tested with our product yet and is actually a revision ahead. Make sure that whatever you have on the PIMG when it arrives has the correct firmware required per the docs from CCO. Many customers call in with PIMG issues and the first thing we look at is that very thing and more often then not, they haven't put the proper firmware on the PIMG whether it required an update or downgrade. Just food for thought here.

Hi Tray,

Thanks so much for your additional info here

Getting a "food for thought" answer from someone as knowledgeable as

you means alot my friend!! (+5 for your help here) I'll make sure to do

some serious checking before moving forward.

Cheers!

Hey Tommer,

You have answered many,many of my questions my friend! This

is just another one to add to the long list. I will review all your great recommendations

and may "holler" back at ya when we actually get started. I was looking at the PIMG

Guide for a Nortel integration and it seems like a fairly detailed process

Thanks again TCAT (+5 for your stellar work!!)

Cheers!

Its only "stellar" work because I had suffer through the complaints of random port droppings, bad audio last month during a role out.   It was brutal trying to find the issue.

The document, just follow it.  It is correct (for a change!)    Id recommend setting (1) PIMG up first only.  Then throughly test it for a week or so with subscribers actually using it if you can.   The issues popped up when it became loaded up with calls, etc.

Once you know the the configuration works with Unity, you can then export the PIMG config, re-import the config to another PIMG.  Go through the document and verify the settings are correct and *should* have consistancy in the PIMGs then.     If you keep bouncing between PIMG and CUC or multiple PIMGs, you will be chasing your tail.


If you have CUCM also integrated to CUCM, even better.  Because then you can test each "side" of the integration (SIP or SCCP) and narrow down (if you have issues) which is causing it.

Enjoy!

Hey TCAT,

The word "Enjoy" somehow scares me

Thanks again bud!

Have a great weekend.
