We have a customer that has the NECSL2100. The problem they are having is a bit bizare.
There are times that when you call the main number it will just ring and won't go to voicemail. In this instance it was after hours. Once the customer rebooted the system it resolved itself and went to voicemail.
We have checked with the local telco, its a fiber connection and line, equipment have all been checked. It seems to all point to the phone system but at a loss?
I have a SL2100 that is doing the same thing but with a twist. This system has 8 CO Trunk Line through a
Comcast Modem. It first started with Line 1 (only did it once) in coming calls would just ring, AA would not
answer. Line showed it was in use but when I checked with my butt set on the block no conversation but
had dial tone. To clear had to reboot the system.
Two days later it again happened this time on Line 2. Same parameters, had to reboot again. This time after much
discussion with Tech Support I first called Comcast and told that it is a phone system issue "not their modem". I asked
for the specs on the "Open Loop" timer and was told it was 500ms. Further discussions with Tech Support it was
decided that I should change 81-01-03 to 400ms. Made the change.
To test I would dial in over the next few days on lines 1-4 and always got the AA. That was 2 weeks ago. All has
been good until yesterday. I was on site and noticed that Line 3 was lit on the phone. I checked and the same
issue. After much discussion with Tech Support it is unclear as to what is causing the problem and what would
be the next logical step to try and resolve.
In an effort to get other opinions I came here. So are there any thoughts or suggestions??
I am happy that at least one other (RWG) has experienced this condition. I don't fell all alone................
Thanks for any input.
