sipXecs, the Open Source SIP PBX for Linux is based on a fully distributed architecture that allows you to leverage any SIP compliant component anywhere in the network. In particular, PSTN / SIP gateways can be added as autonomous devices (with their own IP address) where sipx provides centralized configuration and management (certain vendor's models), and flexible XML-based call routing including least cost routing of calls and load balancing. Redundancy and HA is therefore achieved easily as an inherit feature of the chosen architecture. The sipXecs system also scales using load balancing mechanisms that rely on DNS SRV records and providfe alternative routes on demand to distributed gateways. In particular, this means that for large PBX systems a large number of PSTN gateways and phones register with a few strategically located sipXecs servers. In contrast to other systems, SIP strictly separates between media (RTP) traffic and signalling (SIP) traffic optimizing performance for both.

Digium and Sangoma gateway cards
Digium and Sangoma cards at present cannot be used with sipX as there is no SIP driver software available. However, a PC running the Asterisk PBX or the Yate Telephony Software in conjunction with Digium or Sangoma cards can serve as a media gateway for sipXecs.
