IP-based calling delivers a number of benefits, including lower cost calling, improved quality, additional mobility and flexibility, as well as added features that traditional phone systems cannot match.
Making IP phones work with legacy systems requires a softswitch, however, the digital equivalent to the old switching network we have in our head where operators manually connect calls.
When selecting a business softswitch, there are several factors to keep in mind.
One important factor is how well the system works with current and former calling standards such as SIP, MGCP/NCS and GR-303. It is important to have a softswitch that works with standards and is flexible.
Another factor to consider when selecting a softswitch is how the solution handles data collection. For billing purposes, it is important for softswitches to manage balance status, the number of obtainable minutes for calls (for prepaid tariffs), bonus minutes and SMS info.
A full-featured softswitch also will include billing management, so it is worth looking for a softswitch that not only keeps track of usage, but also assists with customer billing.
A useful feature to look for is interactive voice response that is built into the softswitch. One that is multilingual is an added perk.
The ability to play nice with calling cards of various sorts is another feature of softswitches that is worth noting when making a softswitch selection.
One softswitch that should be on your shortlist is REDCOM’s HDX. It is an integrated softswitch and media gateway platform that delivers interoperable communications to service providers, ILECs/CLECs and private networks. Built on the industry-standard SIP-based architecture, HDX preserves all the functionality and investment in legacy assets while offering safe passage to modern VoIP technology.
HDX includes VoIP call management, media gateway and TDM all in one platform, according to the company. It allows up to 3,000 IP subscribers and SIP trunking, and it is interoperable with multiple access solutions, including SIP, MGCP/NCS (PacketCable 1.5), GR-303 and V5.2. For security, it offers TLS/SRTP/SSL.
The softswitch also provides a high assurance migration solution that enables carriers to schedule a phased approach toVoIP implementation, risks, and financial exposure. Traffic, subscribers, and services are cut-over when it makes sense, eliminating a high risk wholesale replacement.
“HDX facilitates a cost effective way to add packet voice (IP) to an existing TDM switching network, while allowing service providers to retain legacy equipment investments,” according to the company.
