Description:



ImHosted.com - Affordable Web Hosting

We are developing a Business/residential VoIP service.
We will be targeting business. Our phone plans will include unlimited calling in
the UK and international numbers, 4000 minute calling plans for a flat fee in
UK, with single line and Centrex service with multiple line/extensions and
international inbound numbers. We will also have other services like, IVR, Music
on hold, Queuing, Hunt groups and more for our multi user customers. We want to
give every Centrex customer, a reception desk interface for monitoring and
transferring calls to internal extensions and external PSTN numbers. We would
need NAT traversal and SIP proxy; you can use asterisk and SER to achieve that
on two different servers.
The setup that we are looking for should include the ability to configure new
accounts from a web based interface, and online signup and management system for
customers where they can configure and setup there own system including IVR,
Queue, Hunt group, extensions, and also can view invoices.
We would also require a comprehensive billing system integrated for different
types of price plans and packages, and CDR management. We would like to be able
to design and implement these packages and special offers like half price and
free month packages on the web administration interface. Also the bills will be
generated in PDF format and we will need the facility to change them on the fly
which will reflect in the customer control panel. In the billing we will also
need reseller partner facility where resellers can add/introduce customers and
earn commission.
All details will be provided in detail. This is phase 1, in phase 2 we will also
be implementing high availability and web based white label reseller options.
We strongly prefer using Windows based system, using .net and MS SQL rather
then PHP and Perl. In case this is not easy or possible we would like you to be
able to support it for the period or at least one year and train our developers
during that time. Please quote for support separately.
This installation will be a pure IP based solution. Origination and Termination
will be provided via 3rd party providers using either SIP or IAX. We would need
client support on both SIP and IAX.
Deliverables:
1. A complete SER and Asterisk solution capable of handling any number of users
(I understand the bandwidth and hardware limitations, we will consider your
recommendations).
2. Billing module to handle toll calls and over minute usage. It should also be
able to handle the prepaid calling cards and up front billing of the monthly
phone packages. Credit card payment integration for call charges and monthly
line rental. These payments will be processed automatically from this system on
a preconfigured date of every month. Also ability to manually credit any account
using the same facility done on both user and admin control panel website. Also
we will not forget about the customers who can’t pay by credit card, so a manual
method needs to be provided for them.
3. Automatic provisioning of new phone accounts based on the product they
purchased. If they only purchased online and activation of the account as soon
as payment is made.
4. Web interface for users to view call data records and account information
5. Calling card application with web provisioning and online recharge. Calling
card numbers delivered via email.
6. Recording of voice greetings via a handset.
7. Retrieval of voice messages via handset, website and email.
To sum it all, we are looking for someone that can give us a total solution that
will be ready to run and accept customer with an easy to use interface.
