Known Affected Releases

35.1(2)DSP

Description (partial) 

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 "
