Summary:                    [patch] Crash in VoiceMailMain if hangup occurs
before a valid mailbox number is entered (IMAP only)
Description: 
(this actually is for version 1.4.23.1)

If VoiceMailMain() is called from a dialplan without a valid mailbox
number or with no mailbox number, the user is prompted for a mailbox
number. If they then hangup before entering a number, Asterisk will crash.
This only occurs with the IMAP store.

  Fix a potential crash situation when using IMAP voicemail
  
  If calling into VoiceMailMain when using IMAP storage, it was
  possible to crash Asterisk by hanging up the phone when prompted
  for a voicemail mailbox. This patch fixes the issue.
  
  While it may appear that this patch is superficial, it allows code
  execution to continue to the failure case just below the IMAP_STORAGE
  code block where this patch has been applied
