Softswitch
Assignment: The client for this solution was an VoIP service operator. The request was to develop a complex solution of an VoIP software switchboard able to identify, connect and charge the connecting clients of VoIP network (software and hardware end user devices). The used communication protocol was H.323v4 with the option of SIP extension. The product was supposed to have a robust design concept, on the side of load management as well as maximum redundancy of the whole system under any condition. The solution was supposed to have a separate DB part (was to be used a platform and supplier independent , but with sufficient output and security). The system configuration was projected for the database environment, billing, administration so that it was possible to further adapt and extend the system's functionality in the future according to the requirements of the operator. Softswitch was supposed to be design as a multiplatform capable to support applications in various OS.
Solution:
Just from the brief assignment description, it
is obvious that the given project was one of the most complex and
demanding systems realized so far by our company. Therefore, there has
been a team of skilled programmers assigned to the project. The
preliminary analysis and concept proposal took us 3 months of work. The
outcome was a design proposal of the whole solution satisfying the needs
and requests of the client. A concept of various applications
development creating the whole Softswitch solution has been adopted. The
first application was a Command Center, that has the function of main
managing center allowing the authentification of single network users.
The Command Center communicates with the central database, where all the
information about the users and parameters of the provided services,
billing information, etc. are stored. Another part of the system is the
Gatekeeper, that has the function of single users registration (end
points) of the H.323 network. Gatekeeper is interconnected with the
Command Center. The suggested design has been build that there can be
more
n-command centers created in the network with n-gatekeepers connected to
them. Each of the command centers can be located in a
geographically different location and is interconnected via Ethernet
protocol. The same applies to gatekeepers that can be on a various
places in the network. Another projected components in the network were
H.323 / E1 voice gates, that allows call routing and connecting from/to
the VoIP network of the operator to/from PSTN networks. The number and
geographical location of the gates in the system design is unlimited,
what makes this solution one of the most robust and scalable systems
available. Detailed description of the whole solution is very complex
and can be found in the VoIP products section at the Voipac web site.
