Could you upload one such file, preferably .wav ?
you can find them at  /var/spool/asterisk/voicemail/<context>/<box>/INBOX/

It's possible that you can solve this by setting the following in voicemail.conf

<<<
; How many seconds of silence before we end the recording
maxsilence=5
; Silence threshold (what we consider silence, the lower, the more sensitive)
silencethreshold=512
>>>
