First thing I'd do is to put a multimeter across the fxo tip-ring and look for disconnect supervision. In the US, that's typically a momentary open (no voltage) at the end of a call.
Some centrex equipment can be configured to provide it while others don't have such a feature. If you find a difference, ask SBC to provide on your lines. ------------------------ > Has anybody successfully setup an Adit 600, FXO via Kewlstart on a > Centrex line? > > My setup: > > Test system: > > Asterisk (Current CVS - 12-08-2005) > Adit 600 with 1 FXO 8 card > 1 Loopstart (Centrex) phone line from SBC (Battle Creek, MI) > Channel bank setup as lscpd on the FXO card. > Asterisk signaling is FXS kewlstart > > Incoming and outgoing calls work fine. > > Semi-Production box > (Communications between facilities full time, 2 outside lines). > > Asterisk (Current CVS - 12-08-2005) > Adit 600 with 1 FXO 8 card > 2 Loopstart (Centrex) phone line from SBC (Livonia, MI) > Channel bank setup as lscpd on the FXO card. > Asterisk signaling is FXS loopstart > > My scenario: > > My test system using either loopstart or kewlstart works just fine, but > call disconnects take around 9 seconds before being detected. > > My semi-production box, running loopstart never detects disconnect and > times out before hangup, switching to kewlstart, disconnects are > immediate.
