Below find information on key features in this solution. Modules can be enabled or disabled to meet customer specific requirements.

System Design and Features:

Session Border Controller : SIP session border controller providing security for the internal network of the carrier. It also provides NAT traversal support.
- Integrated session border controller signaling & media control.
- Distributed media control only and/or signaling control.

Multi-Protocol:
-SIP, H.323
- SIP-H.323 & H.323 interworking
- SIP & H.323 load balancing & routing
- H323
- PRI (PRA) ISDN PRI (PRA) ISDN

Codecs:
- G711
- G723
- G.729A and G729B
- GSM
- G726

VOIP to PSTN Gateway: Supports TDM and SS7 Networks connections.

H323 to SIP proxying: Giving you an added bonus on how you'd want to send your calls to the PSTN.

Least Cost Routing: Least cost routing to the PSTN based on price, carrier quality, available routes or a combination of both.

Billing Support: Supports all radius billing systems and any database log based billing systems. Current production environment using billing systems running on FreeRadius and Radiator.

IVR
- Unlimited voice phrases/languages
- Very powerful full featured IVR’s can be developed using C, C++, Perl or PHP
- Recording
- DTMF support
- Time Conditions
- Call routing from IVR
- Making multiple call legs from an IVR

Database Support: Support for My SQL and Postgres Databases
- Call Detail Records (CDR)
- Call Accounting records can also be written to the database allowing for interoperability with third party billing systems that do not have radius support.
- Database routing of calls

Security:
- Session border controller DoS protection
- Access control
- Topology hiding & privacy
- VPN separation
- Service infrastructure DoS prevention

Service reach maximization: NAT traversal, protocol inter working, transcoding, address & response code translations. 

Service Level Agreement (SLA) assurance: Admission control – session agent constraints, bandwidth, policy server, QoS-based; QoS marking/mapping; QoS reporting.

Revenue & profit protection: Bandwidth policing, QoS theft protection, accounting, session timers, routing & load balancing.

Regulatory compliance: Emergency services (E9-1-1) & lawful intercept for call data & content (CALEA).

High availability: Check-pointing of media, signaling & configuration state ensures no loss of active calls, or call state required for NAT traversal, session handling (transfer/hold, etc.) or accounting.

Management: Easy to use web interface
