Strange problem with VoicemailMain

Dear all,

I am having a very strange problem with VoicemailMain. When using this application to record unavail, greet, and busy, I an see the corresponding file gets created in the <…>/default/<SIP #> directory. When pressing “1” to confirm the recorded message, the *.wav file gets deleted from the file system.

How can this happen? I can’t figure out why. Is there any option I need to turned on to enable the recording of greeting?

Thanks alot for all your help.
