Flexible Deployment Options

  • Common code base across all SBC platforms.
  • Common deployment and management end to end:  CPE to Carrier/Provider

 

Carrier Hardware Appliance

  • Redundant Power Supply AC & DC
  • RAID SSD
  • 1U Rack-mount
  • Telco standard size 20"
  • Calls Per Second (CPS) - 75
  • Capacity - 4000 sessions (4000 calls)

Enterprise Hardware Appliance

  • 1U Rack-mount
  • Small footprint
  • Calls per second (CPS) - 10
  • Capacity - 250 sessions (250 calls)

 

Virtual Machine (Software Only)

  • Software Only
  • Refer to VM Below

          

        

Virtual Machine Ready

 

Description

  • Ability to run SBC is software only mode.
  • Ability to run inside a Virtual Machine.

 

Lower Price

  • Customers that have existing VM infrastructure do not have to go through the expense of yet another box.
  • Another box requires power,space, cables and offers another point of failure.

 
Redundancy

  • VM infrastructure provides unmatched flexibility, redundancy and durability.
  • VMWare ESX infrastructure can run a single VM on multiple HW platforms allowing carrier grade  Flexibility  hardware redundancy.
     
  • VM instance can be moved, copied and backed up. 
  • VM offers upgrades with minimal down time by allowing IT to build and test new VM before shutting down the one in production.

 

Limitations

  • SBC running in VM as a software only solution will have limited capacity.
  • Limited capacity is primarily due to RTP media flowing the the VM.
  • Software Trascoding will further reduce the capacity.

Scale

  • Ability to scale while running in VM mode.
  • Full Transcoding any to any supported.

Sangoma Exclusive

  • No other vendor supports such solution

 

Easy to use WebGUI

  • Sangoma SBC uses a modern WebGUI for configuration, operation, troubleshooting and management.
  • Other vendors use complex CLI and text based interfaces

 

Documentation built in

  • Along with a standard user manual, Sangoma SBC documentation is embedded in the GUI.
  • Each GUI field has a help button to display the function and feature of the field.

 

Dashboard Stats

  • View SBC Traffic and capacity on single page.
  • View call statistics (CDR) and error statistics (RTCP) from the GUI
  • Ability to search and identify bad quality calls and pre-empt the customer call.

 

RESTful API

  • Sangoma SBC's provide RESTful Web API for automatic easy provisioning.
  • A third party SoftSwitch or application can easily view SBC configuration via Web API's.

 

VI and EMACS in the Browser

  • For advanced users, Sangoma WebGUI offers vi and emacs editors in browser for rapid routing rule editing and development.

 

 

Simple Licensing

  • Sangoma has very intuitive licensing model.
  • Product is licensed based on number of sessions.
  • A session is considered a single leg of the call. Thus two sessions are needed to complete a full duplex call.
    Example: 4000 session SBC can provide (4000 call capacity)

 

Simple  and Predictable

  • Aside from sessions licensing there are NO
    • Per feature licensing
    • Per user licensing
    • Per codec licensing
  • All features, codecs are included in the license.
  • Sangoma only counts INVITE as a session.
  • This allows a network planner a predictable SBC capacity in every situation.
  • Other vendors use draconian licensing schemes 
    • Example: Phone "Registration" counts as a sessions when the call is made
                      In this case SBC capacity is reduced further due to licensing model. 

 

Media Anchoring and Complex Calls

  • Proxy based PBXs require Sangoma SBC when connected to a SIP trunk. 
  • PBX need an SBCs in order to perform complex call functions such as blind transfers and call forking. 

 

PBX Isolation

  • Sangoma SBC is able to isolate the enterprise PBX from the ITSP and provide rich media functions.
  • Without the Sangoma SBC acting as the demarcation point between the PBX and ITSP, unwanted SIP messages such as REFER would reach the ITSP.  
  • In such cases ITSP would simply reject such messages causing call failures.
  • In other cases ITSP has strict rules as to which call flows are supported and allowed.

 

SIP-X and Ezuce

  • Sangoma full interoperates with SIP-X based PBXs and facilitates secure demarcation point,
    while offering media anchoring support to the PBX.

 

 

Advanced XML Routing and Database Support

  • Sangoma SBC's have SoftSwitch style routing plans.
  • Users can configure unlimited number of dial plans/routing rules per sip profile.
  • All routing plans can be applied live without system interruption.
  • The rules can be very simple or very complex.
    They support complex syntax for advanced logic and customization.

 

Database Support

  • Complex routing rules, DIDs, and ACL lists are usually stored in internal or external Databases.
  • Sangoma SBC support external database access via HTTP requests.
    • On each routing table entry an HTTP request to an external DB can used to fetch routing information.
  • Sangoma SBC support internal database via mysql for routing plans, ACL lists and etc.
    • On each routing table entry an HTTP request to an internal DB can be used to fetch routing information.
  • HTTP access allows user to map any DB info into the Sangoma SBC routing logic.

 

Per Message Routing and Header Manipulation

  • Routing rules are executed for each SIP message.
  • Actions can be taken based on any SIP message that flows through the SBC.
  • SIP Headers can be modified using regular expressions for each SIP message.

  

Advanced Networking

  • Most large networks require complex networking support.
  • Sangoma SBC supports: VLAN, DiffServ, QOS, Firewall, etc.

      

Load Balancing and Least Cost Routing

  • Sangoma SBC offers carrier features to the Enterprise SBC.
  • Load Balancing allows Sangoma SBC to distribute call load to number of ITSP providers.
    • In case of ITSP failure, the call load can be re-routed to other ITSPs.
  • Least Cost Routing tables can be used to route calls based on route costs.
    • Takes advantage of favourable rates.

     

Media Server and Transcoding

  • Sangoma SBCs offer rich media services along with full featured Transcoding.
  • VQE Features
    • Echo Cancellation, Noise Reduction, AGC, etc...
  • Codecs
    • G729, G722, AMR, etc...
  • Fax (FoIP)
    • T.38 Pass-Through 
    • T.38 Gateway (Roadmap)
    • T.38 SRTP (Roadmap)

 

Configurable Load Limit Messages

What separates the Sangoma SBC from others is that when this threshold is reached the 
SBC will reply with a SIP 503 Service Unavailable message which tells the originator to try an alternate destination.
In other SIP appliances once the CPU threshold reaches a certain point the traffic is disrupted by means of calls 
dropping, loss of RTP (if media is flowing through), or registrations becoming corrupted.

 

Configurable Load Limit Message

  • Sangoma SBC allows one to configure the load limit message: 501, 403 etc…
  • This allows greater flexibility and customization to custom network needs.
  • No labels
