I have an SX-200 ICP installed at a school.
When we test the CO lines on the RJ21X and with the phone room phone the volume is fine.
But many station users (ONS and DNIC) complain of low call volume on inbound and outbound calls. I have called in from my office and get the same problem, but it happens intermittently.
We have tested the LS/GS cards and find no problem. It does not seem be confined to any specific trunks.
Any ideas?

Are the trunks all on the AOB?

"It does not seem be confined to any specific trunks."
------------------------------------------------------------------------------------------------------
This may sound flippant, but I'll bet you don't have calibrated ears. You need 2 things. A loop tester, and the milliwatt 1004 htz phone number. The tester isn't cheap, but you may be able to rent/borrow one here. The phone number, on the other hand, well, do you have any friends at the LEC? If you are using trunks, they have a designed circuit that is supposed to bring that tone in at -4db to -6db. (It leaves the C.O. at '0'db) If it's a POTS, you're screwed because the LEC doesn't care until the tone is under -8db and that level depends on what the LEC's standards are. They may not care until it's -10db or worse. And I'm here (or hear smile ) to tell you that -8db is NOT a good level for anyone with background noise or a VERY mild hearing loss. (Most folks under 60 that destroyed, or are destroying, their hearing with LOUD music are in that boat. Those over 60 are in the same boat because their ears are going the same way other parts of their body are going, as in 'to pot'.) The healthy human ear can detect a noticeable change of 3db, which is technically a doubling of the sound power. Anyhow, the point of this dissertation, is that there 'probably' is nothing wrong with the Mitel. But, without the loop tester and the milliwatt number, you are not going to be able to prove it. UNLESS you can lay your hand on 2 loop testers and 1 of them has a milliwatt tone generator. And some do. Sorry to be the messenger, but I doubt you'll come to Fayetteville to 'kill the messenger'.

Sorry for the delay in reply.
1 - No, the trunks are located on the AMB and two LS/GS cards in a p-node.
2 - No, I don't have a tester and telco said all circuits were good (If you can believe that).
3 - Internal calls are fine.
Thanks to all!

Did you run the LS_Measurement tests in Maint? I have had issues with the AMB before but there can be a faulty LS/GS port as well.

If you have not run the tests do so because believe it or not, I have had different settings for lines from the same provider from the same CO and Dmarc.

Have the customer keep a log of the low volume calls,( line #, date time, number called or poerson calling in)and capture SMDR in case the customer does not get the line number. This of course assumes the CO is sending CLID.

I have also put the TG in Terminal hunt, pound calls out and one by one move the first line to the end of the line and see which ones have problems. It's a real PITA but sometimes it's faster than relying on the customer to log calls.

Thanks,
The problem also exists on trunks on the LS/GS cards, but I think I will run the LS test and then put those trunks as the first 6 outgoing in a terminal hunt and see if the complaints drop.
They don't have heavy traffic very often so it should tell if I am on the right track.
