anyone seen this before?
DXP+ with a t-1, wink start, e&m dnis.
everything works fine. t-1 provder installs new circuit and we just move patch cord from old to new circuit.
outbound calls over t-1 work fine, inbound works then stops and callers just get fast busy. provider doesnt see errors and i dont have any in error log either. provider states that the calls are being sent back to there switch.
unplug patch from t-1 card and then plug back in and everything is good for a day or two. provider is getting alot of glare from the switch.
i have replaced t-1 card and sync card and still having issue
any ideas?

Who is the carrier? Is this from some sort of softswitch? Also how about the signaling. NI2?

OneComm supplies the t-1. the patch cord leaves the dxpt-1 card and plugs into a cisco router they(carrier)installed.

not a PRI

4 digits, wink start, e&m dnis

sounds like some sort of wierd soft swicth. I wish I had some magic with this but I bet it is One. Good luck on this one.

one more thing. Who is providing sync and what do the logs show when the issue happens. ANy errors like slip?

you know how it works, pointing fingers at each other.
nothing in error log and no alarm lights on board.provider connects t-bird to t-1 and gets same issue and tells me the t-bird is broken.
provider has adjusted there wink-wait timer and everything has been working the last two days
normal settings 1,6 are on sw1, 6 on sw 2 and 2 on liu

I love the t-bird is broken line. That is classic
