Hello Godfathers of Telephony,
Over the last year or so we have been having an issue with analogue trunks experiencing a periodic out of service / loss of dial tone. We now have several systems installed that have exhibited this problem. The common denominator has been Verizon CO lines, never had an issue with Comcast. We are trying to understand if the issue is with an IP Office trunk setting, a hardware issue or Verizon. Here are some details:
- The customer of course advises that they attempt to make an outbound call and they do not have an available line or they have a line that is ring no answer.
- A system status review indicates that every line on the (ATM V2)daughter card has been out of service numerous times with an indication that the line was out recently.
- Our techs have gone to the customers location and connected their butt-set to the line directly at the NID, received a dial tone but have found that an incoming call was not ringing in on the first inbound call. Then, on the second inbound call, the line cleared and they could receive a ring.
- Speaking with a Verizon tech about the issue he said that the IP Office seems to be sending a "wink" and after several winks the CO switch is placing the line out of service.
- We have tried disabling auto impedance but outside of this we cannot see a setting that would remedy the issue.
Thanks very much for any thoughts and suggestions!
