Divmod Sine is a standards-based voice-over-IP
application server, built as an offering for the
Mantissa application server platform. It owes much
of its development to the Shtoom project, which
implements a soft-phone in Python. Sine provides a
SIP registrar, SIP proxy, third party call
control, voicemail, and configuration through the
Web based on Divmod Mantissa.
