I am connecting 1.4.22 and dahdi 2.1.0.3+2.1.0.2 to a siemens hipath 300 and siemens hipath 4000. (2 channels to each switch) with a TE210p card setup as T1 with em_w. When the call is initiated to either switch the phone rings, when its answered then nothing... I hear no audio etc... After the timeout period the call is hung up. The phone switch 300 needs the T1 reset as the channel is not freed up. Anyone ever ran into this? What might be going on? Its installed on a new dell poweredge 860. Incoming calls I never see the "starting simple switch"... ---------------------- loadzone=us defaultzone=us span=1,1,6,esf,b8zs e&m=1-2 span=2,1,6,esf,b8zs e&m=25-26 ----------------------- the card is on its own interrupt.
