My customer converted to AT&T Fiber with the CO lines broken out to SIP/analog on the AT&T ports, now after the move the customer is stating that they cannot hear the caller and what I experienced myself that I could barely hear them when I called.
The problem appears to be intermittent and in house calls sound fine.
I've done the calibration per NEC tech and that hasn't solved the issue.
I'm going to take a CO line simulator to site to compare My line versus AT&T
Any suggestions would be appreciated.
Thanks,

If the cabling is good and the only difference is the carrier as they say..... | | | | Joined: May 2004 Posts: 325 Member | OP Member Joined: May 2004 Posts: 325 | Thanks for the reply,
Earlier today I used my Viking dial tone simulator in place of the AT&T SIP/ANALOG lines and there was a major difference in call quality in terms of volume & clarity so I ask the customer to get a vendor meet between myself & AT&T, I need to make note of requesting g7.11
