IP Office 550v2 Nasty Buzzing Noise - Incoming and Outgoing Calls - Verizon Fios

[mattspotya]

We moved our office to a new location, Verizon came out and got our lines setup and we installed our new avaya ip office 500v2. Calls internally to other extensions work perfectly. Incoming calls and outgoing calls make this constant loud buzzing sound. I tried changing the gains to see if that was the issue but it made no change in the noise. I tried changing the trunk type from Loop Start ICLID to Loop Start and that made no change. The noise is very similar to the one posted here

but it will keep making the noise.

If it helps, anyone can call the line and when the system picks up you can hear what I am describing 951 600 2577

We have a really helpful Verizon tech that stopped by a couple times to check their lines to make sure everything was good.

We also overnighted a new control unit to see if that was the issue but it didn't change anything.

Any insights anyone has would be greatly appreciated!!!!

Sorry posted the title wrong, IP Office 500V2 not 550... Running on 3 hours sleep at the moment...

Induction can do this. I had the same issue with a company that was located near a radio tower. We had to install shielded cable to fix it. You need tome test tools to isolate which end the noise is coming from. You probably should hire somebody to check it out. You're in Murrietta I am in Claremont.

I would check the lines before it goes into the system. to narrow things down. I take you have a phone to test the lines with....

 

[mattspotya]

We tested with a regular phone in the test port on the Verizon box. Worked with no problem.

pmcook, is testing the lines a service you offer?

You changes the control unit - but did you swap out the trunk card?

 

[pmcook]

You tested the fiber side of the deal but depening on how long your cross connects are they could be possibly picking up interference from a strong magnetic or electric source. Or if their is a induction motor nearby. The quickest way to see would be to remove one of the lines at the trunk card and using a coupler plug an SLT in or plug directly into a phone if you can and see if you hear the sound.

The Verizon tech plugged his butt set in between the phone and the system. The noise could be heard when the 9508 picked up the phone but if he intercepted it with the butt set there was no issues.

This has been noted before I believe and on more than one occasion, it's an incompatability between the modem they use to present the lines and the system, I think trying a different model modem can resolve the issue.... if I remeber correctly

 

[mattspotya]

Interesting, I will look into the modem issue. We did take the unit to our old building which is just around the corner and it worked perfectly. The Verizon tech mentioned on the phone that it might be a voltage issue. Thanks for the input on the modem, hopefully I can get them to change it out.

 

[amriddle01]

No worries, make sure it's a different make not just a new one

 

[mattspotya]

I just called my Verizon tech and he told me there is no way they will put in a different model since we have the latest one. Our old office has an older model and it works over there. This is driving me nuts!

 

[amriddle01]

It's all pointing to the modem isn't it

 

[amriddle01]

Can't you just swap the modem yourself?

 

[mattspotya]

Are we able to do that? I wasn't sure if there was some kind of activation that needed to happen. If not I'll go do it right now!

 

[amriddle01]

I don't know, I'm in UK so we don't need such things and I don't even know what one looks like. Can't hurt too much to try.... depends how brave you are feeling

Matt,

I found these links that might be helpful:

When in doubt, just keep upgrading! LOL

 

[pmcook]

What modem? The Actiontech is a broadband wireless router. This is a fiber service. Verizon uses several different devices depending on the type of service you have. These are not replaceable by the end user. I'm not even sure there is a modem involved at all since they convert a digital signal to analog using a DSP. Verizon won't tell you this but they can be adjusted. You just have to make them listen. You could attempt to use this as ground for early contract termination which may light a fire under them. If not, you may have to switch CLECs.

 

[Kierso]

The other options are If the line to the system was tested with a standard Analogue phone is to Upgrade the firmware on the IP Office, If your lucky it will clear your problem.

We got it working! We were moving equipment to the new office and my boss found one of our old DSL line filters. Out of desperation we plugged it in and can now make outgoing and incoming calls. Went out and bought more for our other lines and all is well. I really appreciate everyone's help on this issue!!! Hopefully this post will help someone in the future that might run into this issue. Thanks again everyone!
