Secondary Dial Tone

By default, if someone picks up a Cisco phone the "inside" dial tone they hear sounds like a normal dial tone from the PSTN.  If they dial "9" to get access to the outside world, they get the Cisco "outside" dial tone.  One of my cleints hates the sound of the outside dial tone because they say it makes the phone sound like it's broken.  No problem, in CM Params. I just made the outside dial tone sound like the inside dial tone.  This works great on all of their 79XX phones.  However, it doesn't work on their 9951 phones.  When a person picks up one of those, they get the "inside" dial-tone just fine, but they don't get any "outside" dial-tone at all; they just get silence.  Is there anywhere I can go to configure the outside dial tone for the 9951 so it sounds like the inside dial tone, or am I out of luck?

Re: Secondary Dial Tone

The phones that you have it working on--are any of them SIP loads?  The 9951 is a SIP phone.

Does the 9951 play secondary dialtone if you don't customize the outside dialtone?

Could be a bug with the 9951--it should be playing secondary dialtone.  I'd test with the latest firmware posted for the phone, and if the issue persists, get a packet capture off the phone and open a TAC case to get this looked at further.


Re: Secondary Dial Tone


Which parameter in CUCM are you talking about specifically.

I just tested here in my lab and I get both Inside and Outside Dial tone on my 9971 phone (which should be similar to your phone).

I get inside dialtone as soon as I go off hook. I then press 9, which matches my 911 lab translation pattern that has "Provide Outside Dial Tone" checked, and I receive Outside Dial Tone.

Do you mean the CUCM Service Parameter "Always Use Dial Tone Setting" is set to "Inside"?

I'm testing this now in the lab and will let you know my results.


Re: Secondary Dial Tone


I just tested this parameter here and I was able to reproduce the problem you're talking about.

When I set the Always Use Dial Tone Setting to "Inside" and go off hook on my 9971 phone, I get Inside Dial Tone. When I then press 9, I receive silence!

The behavior on a working 7961 phone is that I go off hook and get tone, and then press 9 and hear a short beep, and the Inside dial tone continues just as before.

I then changed this service parameter to "Outside" and noticed on the 7961 phone that Outside tone was always heard.

On a 9971 phone the behavior was quite broken! Going off hook I received Outside dial tone, but then after hitting 9, I received Inside Dial Tone!

This definitely looks like a defect. Can you open a TAC Service Request to get this issue addressed? If your CCO profile has access to a Service Contract, you should be able to look over on the right hand column of this forum and find the "Open a Service Request" button. It will transfer the contents of this discussion straight into a TAC Service Request.

Once the Service Request is resolved your TAC Engineer can update this Support Community Discussion with the steps taken to fix the problem. Thanks for bringing this to our attention!


Re: Secondary Dial Tone

I converted my lab 7961 phone from SCCP to SIP. It now has the same problem as the 9971!

That means this isn't a problem with the 9971, but a difference in behavior between SIP and SCCP phones. (The 99XX phones are ONLY SIP).

I'll have to look into this a bit further.

Re: Secondary Dial Tone

Thanks for all of the information Jason. I'll be working on it, so I'll let you know if I come up with anything too.

Re: Secondary Dial Tone

Hi Refram,

I got same issue for sip phone 9971 and 9951, Do you have the solution ?

Re: Secondary Dial Tone

Nope.  The client decided that they didn't care as long as they didn't get the "inside" secondary tone.  Around about the same time that this came up, a different, very large, issue came up and I never got back to this one.  I haven't checked any new firmware to see if it is still and issue.  Now that it's back in the front of my mind, I'll probably do so.
