only when i use a playback_separator to append multiple files to be played.... i checked switch_ivr_read and switch_ivr_collect_digits_count functions but everything seems to be ok there... can anyone help locating the problem ? Ps: im running freeswitch@cxss01> version FreeSWITCH Version 1.0.6 (svn-exported) tried with Revision: 17032 before this one but seems to be the same....
