For large and complex installations, sipXcom provides high reliability, rich functionality, significant reductions in capital expenses (CAPEX) and significant reductions in operating expenses (OPEX). CAPEX is reduced by cost-effective features such as sipXcom running on standard Intel and and AMD servers under open-source Linux and the freedom to competitively purchase hard and soft phonessoftphones, gateways, switches, etc. from many different manufacturers and vendors. OPEX is reduced by the ability to auto-provision phones, centrally administer the system, ease of use and least cost routing.
To get started exploring sipXcom, you can set up an almost free demo sipXcom system. A public cloud installation for demo and testing can be set up for about $20 per month. A domain can be acquired for as little as $1 for one year. SIP trunking can be set up for $1 per month for a DID telephone number and 1c per minute for incoming and outgoing calls in the USA. Softphones such as LINPHONE are open source and free. Other low-cost options are to install sipXcom on open source VirtualBox or an existing CentOS server.
