Paging under water

[djuplift]

I have an IP500 running 4.2.11 with 100+ ip Extensions, they have an "AllCall" page group maxed out with 64 extensions all IP except the one analog overhead page.

We have pages that consistently sound like they are under water..

My thought is its most likely network related however, I'm not sure, anyone seen this before or have any ideas where to look?

If you set up another group with just 10 phones does it work better?

LOL, at first when I read this I thought you were looking for suggestions on speakers to place in a Swimming pool or Shark Tank/Aquarium to be able to page Fish or divers.

 

[djuplift]

I told them to try something like that smaller groups etc..
I also have them watching the switches during pages 64 IP phones is a big broadcast after all.

No Shark Tank paging going on here just yet...

How many free VCM channels do you have just before the page ?

It might be as simple a feedback. Try a page without the overhead and a page to just the overhead to see if they are any better.

If they do it may be a case of simple doing the page from a location less prone to hearing the page at the same time.

Gah - I must admit I was intrigued by the subject. Intrigued by not only the near impossibility of paging underwater, but by whatever possible situation which would require paging people underwater. "Boss wants every worst-case scenario covered i.e., the levees break and our warehouse floods, he'd like to be able to page people and let them know the water above their heads is due to flooding" Because, you know, it is not official until the boss says so.

So, yeah, slightly bummed that it has nothing to do with that. However, we had a similar situation where the pages sounded less than lifelike. I thought it sounded like demonic robots but I can see how one would think it sounded as if it were under water. For other reasons, we had to double the amount of vcm channels available and as a result none of the pages have since sounded evil. I cannot say for certain that is the cure all, but it definitely seems to have worked for us.

The cheapest route, though, would be to definitely try Sizbut's suggestion. I know firsthand the hijinks and hilarity of an IP phone's speakerphone overlapping another.

72 Free VCM's, we have already tested the paging without the overhead page in the group.

I have also been informed when the underwater sounding pages occur they do not disconnect properly after the station goes on hook.

You never answered my question.

Notsetinstone they have smaller page groups and they all work fine.

So don't you think that might be the answer?

Just because the docs say 64 is the max doesn't mean they are correct.

Maybe the docs should say:

"64 telephones supported on IP500 (as long as it works) otherwise it will be some number less than 64. Keep adding phones until it doesn't work properly, then subtract one, and go with that number"

It works fine most of the time this doesn't happen on every page. I see it as a network issue i posted it here to see if anyone else has had a similar issue that may have some idea of what can be done to make it work.

If all pages come from one operator disable AGC on just that phone and see if it makes a difference.

LOL @ notsetinstone...

I am also disappointed this post wasn't about paging under water, although I took as wanting to page FROM under water...

I have of course tried to page more than 64 ip phones before Avaya even had specs on paging groups. They claim it only uses 1 vcm resource during the page, as long as all the codecs are set the same. Using Extreme Switches with seperate VLAN's I couldn't page more than approximately 48 at the same time on the 412. (which happens to be what the specs say)
