asterisk users - Mar 2003 - Beginning of voicemail missed by sip phone

Hi,

We are testing a number of sip phones from different manufacturers. With one
phone in particular, when I dial the asterisk voicemail, it misses around half a
second from the beginning of the announcement. I don't have this problem
with the snom 200 or 100.

Does anyone know why this happens? Is it a sync issue? How do I delay the start
of the voicemail announcement? (Maybe that will fix the problem).

Thanks

You can playback a second or two of silence ...

regards
Martin

Actually I've seen this exact issue with my Cisco 7960.
And it's any voice prompt I dial.  I loose just the very first .5
seconds of the audio for whatever reason.
So the sip users hear "eedian Mail" and "nk you for
calling".
Any one else dealing with this?
Any ideas?
