Cross Talk on Avaya IPO 8.1 Continued

[bbaits25]

I had a tech an AT&T tech come out and check the lines coming into to verify they were not wet or damaged etc. He told me it was something internally. We replaced out IP phones to digital phones about a month ago and this is when it started happening. They were having call quality issues in the past with the IP phones so we opted to do digital which they are better but now the cross-talk is happening. Any idea's that could be causing this.

Thanks!

I'm assuming that you are using POTS lines? If so, I would change the cable between the KSU and demarcation. Next step would be changing the ATM, or Combo card.

 

[bbaits25]

Yes we have 12 POTS. I haven't changed the cable between the KSU and Demarc yet. I have replaced out the whole IPO system (the case and all the combo cards and ATM's).

 

[Telecomboy]

If it is actual cross-talk, there was a bad batch of combo cards that went out that this effected. Are you using the newer Combo card or is this an older version combo card? It could be you have an older combo card that has this issue.

1st question , is the call that is being overheard one that is taking place on your IPO?
if not then it has to be a network provider issue.

if it is then Telecomboy is probably correct about the faulty batch of combo cards.

[bbaits25]

We have the Combo Card v2 and the ATMv2.

Yes cross talk happens internally when another user is on a call. Doesn't happen all the time though....

What type of cabling do they have internally?
Crosstalk on digital phones is something i have never seen.

BAZINGA!

I'm not insane, my mother had me tested!

 

[IPGuru]

it is time to replace either the cards or the main unit.
are the phone with the problem all on the same card or doe it happen between cards. if between cards change the CCU otherwise replace the card.

This should all be being investigated & resolved by your maintainer.

Only time I have seen this on Dig phones is when it was the lines at fault, the AT&T tech wouldn't be able to tell unless he had several test butts/handsets plugged directly into the lines and made several calls. BUT if you get crosstalk on internal calls then it is the system/cards if it's just on the lines/external calls I still would lean towards it being the lines

The cross talk happens on calls that come in or external calls, the cross is only noticed internally when other employees are on the phone and can hear fellow employees conversations only that person not the person they are talking to. These are brand new cards that we bought when we replaced out the IP phones. Do you think its a cabling issue?

 

[mforrence]

Do you think its a cabling issue?

Unlikely with digital communications. MOST likely is LEC - but catching it is a bear. We're dealing with a similar issue and put parallel appearance of all lines on a series of jacks at one "team player" user's desk. When trouble happens, they plug POTS phone into appropriate line to see if they can hear it outside of phone system.

 

[amriddle01]

Aren't calls that "come in" external calls? Does one extn ever hear get crosstalk when talking to another extn (no lines involved) or is it only when 2 internal users are both on external calls i.e could well be the lines

[bbaits25]

when two external calls are in effect and its random extensions.

 

[Telecomboy]

Your best bet is to go on-site with two test-sets and connect to line 1 with one and line 2 with the other. place a call on each and see if the problem exists. If it doesn't, move on to using line 1 and line 3, continue trying each combo of lines outside the IPO (I know 12 lines is a lot to test) until you verify the issue is either present or not. It's a time consuming process, but you will never get ATT to admit it is them until you can verify which lines are the lines that are crossed. The reason it is sporadic is that it is probably just 2 of the 12 lines effected.

Another option depending upon the clients willingness to participate is to label each of the lines in the IPO. When the client experiences the issue, have them record the line they are talking on. Then you will know it happens between lines 701 and 705 or whatever.

 

[amriddle01]

Then you have narrowed the issue to either the line card or lines, do you have the v2 analogue trunk cards? I believe they were released to cure similar issues



"No problem monkey socks

 

[bbaits25]

yes there version 2 cards with 8.1

 

[bbaits25]

I replaced the cables going into the demarc (I ran two seperate cables for the two lines that have been giving cross talk issues). I tested it out by going straight into the demarc with two buttsets and there was no cross talk going on with multiple calls incoming and outgoing. I then did it with the cabling and did it straight from the patch panel into the demarc, put the two butt sets downstairs and tested it out, no cross talk. I have maybe narrowed it down to the phone system, are there any settings or suggestions you guys can give me???

Thanks!
