Softswitch Class 5

The softswitch part is the main element of the platform, which merges the functionality of the following VoIP architecture elements:

• SIP registrar
• SIP proxy
• H323 switch
• H323 gatekeeper
• SMS gateway

Supported protocols:

• H.323 v.2 (H.245 v7, H225 v4) with/without FAST START
• SIP (RFC 3261)
• SMS through SIP, HTTP and SMPP

The main characteristics of the softswitch include:

• Simultaneous and transparent support of SIP and H323 protocols (sip <->h323 translator)
• Various types of proxy methods e.g.full proxy (with RTP-proxy), signaling proxy and other options, possibility of selecting a proxy method per destination, route or per client.
• Full interoperability with industry standards compatible VOIP equipment (gateways. switches, ATAs, terminals)
• Bidirectional NAT support both for SIP and h323 equipment
• Advanced routing system (support for internal virtual prefixes allowing to create separate dialing plans for different groups of customer accounts)
• Routing based on prefixes, priorities per routes, depending on allowed voice codecs per destination
• Support for failover (rerouting), configurable end reasons initiating failover, support for priorities
• Load sharing support - advanced algorithm taking care of traffic being evenly distributed accoridng to defined percentages for multiple routes
• Least calls routing
• Quality routing
• Internal numbering plans support

Various authentication methods:
- by IP address
- by caller ID (ANI)
- by h323 ID
- by SIP credentials
- PIN

• Flexible methods for call setup data modifications (for clients and/or for destination in the dialing plan) :

- modifying dialed number, adding prefixes/suffixes, wild cards, max/min number length
- modifying caller ID/SIP display - adding prefixes/suffixes, wild cards, max/min number length

• Defining allowed and/or primary codecs for clients and for terminators
• Codec autonegotiation
• Import/export accounts and dialing plan from/to excell or txt file
• Settings stored in the MSSQL or MySQL database
• Scalability supported cluster configuration with multiple voipswitch instances running connected in a cluster, sharing SQL database server, thus increasing performance by dividing the traffic among multiple servers while retaining central point of management with one, main IP address for clients (load balancing)
• Redundancy ? support for seamless traffic handover in case of the main server failure, the service allows for controlling availability of particular ports (for example SIP, h323 listeners)
• Real-time SQL data backup procedures
