I've tried to compile chan_zap in asterisk 1.4.2 but it seems that it cannot be done. The configure script of asterisk 1.4.2 checks now on ZT_EVENT_REMOVED and ZT_TCOP_ALLOCATE in zaptel.h, but they doesn't exists in zaptel 1.4.0. Is there a possibility to release zaptel 1.4.1 soon, so I can compile chan_zap.
