Known Affected Releases
Symptom: Call start failing with below messages on the syslog : " FLEXDSPRM-3-TDM_CONNECT failed to connect voice-port (0/0/0) to dsp_channel(0/0/0) " " hwic_t1e1_wic_bp_disconnect: disconnect failed " Conditions: E1 CAS or ISDN configuration on VWIC3-1MFT-T1/E1 When calls comes on E1 CAS but no channel is available so PVDM3 plays a busy tone and create a TDM connection EHWIC:44/25-->PVDM:82/05 . After 10 second this connection should drop but it does not break so any new call that comes on EHWIC:44/25 fails and generate following error : " FLEXDSPRM-3-TDM_CONNECT failed to connect voice-port (0/0/0) to dsp_channel(0/0/0) " " hwic_t1e1_wic_bp_disconnect: disconnect failed "
