ECHO one 5410 digital phones

[peterv05]

We use the IP OFFICE 406 V2, release 3.1 prior to maintenance release 3.1.48. We do not make use of IP-phones, instead the office users (60) use the 5410 digital phone and our 3 operators use the 5420 digital phone in combination with Softconsole. Randomly our office users get a ECHO on the line, which is a PRI-15. This happens with in- and outbound calls, mobile and normal numbers. This problem was first addressed at the TELCO provider (which is KPN by the way), but they did not find any problems related to the line or de PRI-modem they installed.

Is there a setting in de IP OFFICE 406V2 that can be responsible for this to happen? In other words, is there a setting to be used for a form of ECHO cancellation?

I have posted some other questions on this forum also, and while I appreciate all the help, I also got some answers in which is stated that the maintenance release 3.1.48, made available on december the 16th by Avaya will solve a lot of bugs (our issues) that are present in our current release. The technical bulletin (56) of Avaya however does not mention a lot of resolved issues that I can relate to in regard to the issues at our site. Is there anyone who can give me some more information (in detail) on issues that have been resolved with the 3.1.48 maintenance release.

Check out the tech bulletin for maintenance release 3.0 (69) - all issues there are supposedly resolved in 3.1 (48) also.

I've had issues like that, echos and feedback, after a recent install with a couple 5420s and one 5410, it ended up being the 3 actual phone sets which were replaced as a DOA failure, not had any issues since.

it took me a while to pin this down to the same users having the problems, my customer was not setup for trouble reporting, so I setup a call log for them, and after a week or so the log showed the same 3 users phones were the culprit. Might be worth a shot for ya,

I am having the same problem with 5400 series phones on a PRI at two customer locations....I have been working with telco at both locations....they claim the PRI's are ok...please let me know if you find a solution....I will do the same for you....

This can have many sources, among them:
Replace the CAT5 cable between IP Office and modem, make sure the IP Office is earthed properly.
Is the PRI fitted in slot B?
Did you replace the PRI card?
Is the synchronisation set correctly?
Is the locale of the unit set to nld?
Did you use the cables wich came with the expansion units?

Turn off auto gain control on the handsets this is in the 5410 20 menu

I will try this setting with some of the 5410 users who experience this random problem with external calls. thanks for the tip!

My PRI card is in slot A in both systems....do you think this could cause the echo problem ? location # 1 has a 412
and location #2 has a 406V2...

Last week I turned of the auto-gain control on some of the 5410 phones. This setting did not result in the problem going away completely, although it did not happen as frequently anymore, but that could just as well be a coënsidence, because the echo problems occurs randomly.

For now the complete PBX environment (including Phonemanager Pro, Softconsole and VM Pro) has been upgraded with the 3.1.48 maintenance release to see if the echo is fixed, along with some other (more major) problems.

We are having echos on 5410 handsets. sounds similar to your issue.

Lines come in as t1, but phone company de-muxes them with an adtran and hands them as analog to us.

We are still trying to resolve this.

It looks like its grouded properly.

Customer's old nortel didn't have this ussue they say.

No VoIP phones involved.

 

[crashtest1000]

Muxing from digital to analogue will be the issue. If possible get rid of the mux.

Also are the users using headsets try without these.

 

[bigjerms]

Users aren't using headsets.

Same setup with same carrier at another office has no echo.

Carrier came and reconfigured their adtran and then rebooted it and the echo went away for a while then came back.

I'm wondering if its a grounding issue with the adtran.

Others have suggested adjusting the gain on the analog trunk cards.

Customer doesn't want to pay for a pri card and carrier may not let us hook directly into t1.

The maintenance release of december last year for the 3.1 version of the 406V2 resolved our isolated issues with echo with some of our (digital/no voip) 5410 users (not using any headsets). While AGC may simulate a solution, all it does is turn down the volume and in effect also turn down the volume of the echo, but it is still there. Because of other more pressing problems, the maintenance release of december was applied and the echo cleared up.
