VOIP Platform alterations

We are looking for an experienced developer/engineer to make alterations to our VoIP platform and web application.

We are running a windows based softswitch compiled in C#. The database side is MySQL and the web side is aspx .NET

Initially we require an API integrating into our web site to facilitate customer registartion and automatic DID (telephone number)

genearation and allocation. This obviously needs to involve the softswitch application and DB. We also require other work,

the ability for the system to count and allocate 'Lots' of Free call minutes to unique destinations to account holders.

At the moment our system will only allocate 'Grace Period'. Also the ability to provide 'service plans' to customers,

at present our system will only allow normal account generation.. Please submit your response or enquiry directly through


The work should be carried out over 3 stages and costed/paid accordingly per completion of each stage through Escrow only...

Stage 1,

Design and impliment Service plans and Web registration pages to include DID API (facility to provide telephone numbers live on web-site)

similar system is shown at [url removed, login to view]

The web pages need to provision different types of serfvices (5 services) all with different prices,

System to send automatic Welcome email to confirm account setup and account settings to new customer.

The website is .NET on Windows Server 2003, however the API needs telnet or similar to communicate, the API does not work under Windows

Telnet so this needs to be devised a method of invoking the API telenet whilst using Windows Server

Payment process for registration pages is through Paypal on subscription (monthly basis)

Stage 2,

We would like to impliment a method for customers to trace the last inward call. This should be by dialling a preset 4 digit number,

the idea is that the system carries CDR's (call detail records) for both inward and outward numbers called, a way of extracting the last inward number from each individual account via CDR's and then using pre-defined voice files to read the number back to the customer over the telephone.

The system has an engine that is capable of this but as yet does not include this.. This uses Dll and XML files to invoke this type of call feature.

Stage 3,

To develop and impliment the ability to allocate 'Lots of Free minutes' to individual service types.

E.g. service 1 500 free minutes, Service 2 1000 Free minutes.

To alter present system to allow the above by allocating and counting minutes as they are being used. Once used normal tariff applies.

Please PM me for more detailed information and any questions..

Please note the required work is to make alterations and new processes in our existing VoIP Platform, we are NOT looking for a VoIP platform

***Note*** one of the project needs is to be able to use a Telnet program to send and retrieve information during the web pages registration process, for the purpose of creating an account with a UK DID (telephone number) the information sent and recieved then needs to be shown on the web site page and then to be correctly assigned to the new account. The original process is quite simple however the API will not run on windows Telenet. As the website is .NET aspx this is a vital Issue that the winning developer will need to understand and be able to address and remedy quite quickly.

Please note that we require a breakdown of the 3 stages costs and these will be paid for by Escrow on completion of each stage.. The budget could be raised for the right developer..
