MiVoice Office 250/Mitel 5000 / Re: Cannot break dialtone
« on: November 20, 2018, 01:20:39 PM »
after resetting the comcast boxes the on hook voltage went up to 50vdc. that seems right. we will.play the waiting game to see if it happens again and measure voltage if it does.

We went onsite today and measured the on hook is 1vdc and off hook is 17vdc with a butt set and 7.86vdc with going off hook with the Mitel

That doesn't seem right to me.

It was not measured with any DVOM, the tech out there has a Loop Current Tester from sandman.com that has always served him well, everything was green on the tester.

We have an Office 250 HX V6.3 that occasionally cannot break dialtone. Once the system is reset it works fine for a few days. Comcast is the service provider, we have verified polarity is correct.  All four lines in the controller and two on the LSM are affected. We've ran Hybrid Balance and Loop Loss tests but it keeps happening.

MiVoice Office 250/Mitel 5000 / Multicast paging to axis C2005
« on: February 21, 2018, 03:14:40 PM »
Hey everyone, we have a school with a Mitel 5000 HX, they want to add Axis IP Speakers. We have never set up paging over IP before.  I know in programming you cannot add SIP extensions or SIP trunks to page zones. So not quite sure how this could work if they want to page internal phones and overhead speakers.

When we first started this battle we changed the receive gain on the loop start trunks to -3db as mitel had suggested. still the same results.

Ive went through and changed all the trunks to -3 on receive and 0 for transmit.

I contacted AT&T before and requested info on the dB levels of their trunks but was never able to get anywhere. These appear to be traditional POTS lines and not analog from U-Verse.

I changed the values of transmit and receive to 3dB as that what it said. I immediately ran the test again and the output showed 6dB for both transmit and receive.

I did go through each and verified the settings. Obviously I am not able to change the ERL, but did make sure that the Hybrid Balance was set and if not made changes accordingly.
What I do not understand is the Transmit and Gain, Trunk 94005 dB levels were set to zero before the test, the test results show 3 and 3  I changed the values to 3 and 3 and run the test again and they show 6 and 6.  Is this normal?

In response to your question about the flag for "Connected to CO.  The answer is no.

Yes we did run the Hybrid Balance and Loop Loss tests.

OK,  I think I still have some 8520's or 4400's around.  This is a new system in the beginning of October. When we plugged them in they went through the process of upgrading firmware, I remember that same issue but did not see any errors this time around. . I will try it though.

Admin/Diag shows Version 18.00F7.2E.04  Not sure if thats current.

Yes, I should have mentioned that it does the same thing regardless or volume.
 We had a previous system with the same issue and Mitel Support suggested going into OLM and tweak transmit and receive Gain to mask or eliminate the issue. We have tried this as well.
Also we moved phones to another echo profile.

Hey All, 
I have a Mitel5000 with version 6.2.5.82, Digital 8528 phones and AT&T POTS Lines. Users complain of echo (they can hear their own voices in the ear piece) on outside calls. We have ran the Hybrid balance test as well as Loop Loss, I cannot seem to figure out the issue, we have had the issue with IP phones/POTS but never digital phones/POTS.
We have had the issue with others system but once we moved to Comcast POTS lines the problem seems to go away.

Have any others had the same problem?

thank you for that, I did review that document previously, however I was unable to locate the "Config Guide" thats when I got frustrated and asked here for the previous guide. Can you give me direction as to where the Config Guides are located?

Thank you again.

Does anyone know where I can get the instruction manual for configuration of the Audio Codes MP114 gateway and the axxess or 5000?
It appears to not be available on Mitel Online, and I cannot seem to get to the edge.
