I think it can work but both my systems are on public. You can use pstn 
gateway without a DB, in fact if you only have one gateway you can just 
connect direct to it, via you digium interface.

The problem you will face are connecting ser to asterisk, and then 
deciding what should do what, I have asterisk doing all my call pickups 
etc, meetme and all, including voicemail, but since asterisk can also do 
transfers, and routing to other numbers, and so can ser, its can get a 
bit scary.

Also when you have the pbx you wil decide to have another numbering 
scheme, like 3 digit internal extensions, these will need to be done in 
asterisk, and mapped in asterisk, cause in asterisk you can have the 
same extension for diff "companies", I couldn't see howto do that in SER.
