Greg,

How do you think it would be best to start a "best practices"
document? My feelings are that to make the most impact a fully
functional ser.cfg for a real world SIP proxy should be the basis
because most folks on serusers are just looking for a quick "how do I"
answer.

I'd like to think that if I just posted my ser.cfg then the ball would
be rolling on this, however, I doubt that would happen for several
reasons:

* I'm not 100% convinced that my ser.cfg is error free.

* I doubt I've done things exactly correct (ie, I'm sure there are
better way to do some things I've done).

* I've got many inline comments, but a much deeper explaination of key
areas of my configuration are needed.

* My ser.cfg is deeply dependent on external factors, such as our
slightly modified version of Asterisk, which we only use for
voicemail. So I don't think just seeing the ser.cfg would answer too
many questions regarding how MWI works without including Asterisk
integration documentation.

Anyhow, that said I believe that an initial "best practices" document
would need to focus on these key areas:

* Basic ser.cfg structure
* Database usage (enabling/using MySQL)
* NAT traversal
* PSTN integration (ie, gateways)
* Asterisk integration for voicemail only (no call routing logic)

I think that this would solve many of the postings that appear on
serusers frequently.

Regards,
Paul
