[Speex-dev] (maybe OFF-TOPIC:) speex for voice-message/mail application

[Icarus Alivier]

Hi,

This may not be the right place to ask this question, but for the want of a 
better alternative I am posing this query here. Pointing to the more 
appropriate forum would be immensely appreciated.

Are there any existing products / projects that use Speex for discontinuous 
transmission, as in voice-message / voice-mail application ?

Also, what is the recommended container format for speex encoded speech data, 
for voice-mail / voice-recorder type application, i.e. for saving them in files?
If in addition to pure voice, I add some textual tags or annotations, what 
would be the most suitable format / container?

thanks,
ica.
