[Serusers] newbie - implementation guide?

[Rich Adamson]

I'm playing with Ser in a lab environment and have it running as a bare
bones implementation. Can someone refer me to an implementation guide
that might provide an uninformed person some hints on installing and using
important plugins, typical configs, etc?

I'd like to interface with one/two representative commerical IP phones,
maybe a Cisco router voice card, possibly an open source voice mail system,
and a few other items to increase my knowledge/exerience with voice-over
and the system. (Lots of experience in the POTS and protocol analysis areas
but none with Ser, plugins, or voice-over.) Any suggestions for 
hardware/software to try, key web sites, etc, would be greatly appreciated.
