I know this bug.

2 OS500 v2.69 connected via E1 QSIG

Incoming call (via PRI card) to PBX A transfered to Ext# PBX B.
Secretary PBX A wait some seconds then press TRSF key.
But call isn't returned, it's disappear.

External calling party now can hear surrounding area
via Ext microphone Secrectary Stn, or hear secretary call like barge-in.
