With the risk of being bashed on this list, I would propose that you use Asterisk
as a PBX. It can register to SER, it's not a full-featured SIP proxy as SER, but
have the functions you need on the PBX level. Voicemail, conferencing, call groups
and a lot more. SER and Asterisk is a good combination in the scenario you describe.
