Call Waiting Doesn't Beep - UC500/7960

Answered Question
Jan 30th, 2009


I've got my UC500 with a few 7960G phones. Call waiting functionality works but I cannot get any audible sounds to inform me that a call is comming in.

I have tried the 'call-waiting beep / ring' commands but they don't take. The strange thing is, is that the commands are accepted without erro, but when I do a sh run, they are not never there?

I just updated to 4.9 and still the same issue.

Any ideas?

Now I see what's happening here. What you are seeing is expected behavior for overlay DN's. Call waiting is automatically disabled in this case.

Hope this helps,

Marcos Hernandez Fri, 01/30/2009 - 09:05

On button 1 for that phone you are using the overlay operator, something like:

button 1o13,30

So you get both extensions 101 and 1101 to ring on that button. The "o" separator implies "overlay", which automatically disables call-waiting tone (but not visual indication).

A way to correct this is to have DN 30 assigned to a different physical button and leave DN 13 on button one exclusively:

button 1:13

Ah. I see what you mean now. Thanks for your help. I changes the overlay portion of it. I gues call waiting will start working as planned now? I'll test and post.

Wish granted :-)

With the introduction of octo DN's (instead of dual lines) and parallel hunt groups, the need for overlay DN's will be greatly reduced. Both features are available in 12.4(20)T and up.


jaydien1358 Fri, 01/30/2009 - 12:34

That's interesting. I'm not familar with octo DN's. I'll have to reaad up on that. With octo DN's, I could use my original configuration for my buttons and still have call waiting function like it should?

I noticed that 11.4.(22)T is posted, and there is a VOD posted on this site about enabling Live Record where it requires you upgrade to that version. Is that version stable at this point? Should I be concerned about performing that upgrade?



jaydien1358 Fri, 01/30/2009 - 12:58

Thanks for the link.

So is ( a tested SBCS release and safe to use at this point?


Marcos Hernandez Fri, 01/30/2009 - 13:10

Being an Early Adopter package, you do incur into some potential risks, as these releases are not subject to the extensive testing of say, 4.2.9. But if you want to use octo lines, then gives you that possibility. Typically you would deploy this in a test bed before moving it into production (though I understand sometimes this is not feasible).
