Hosted VoIP Server - OpenSIPS, Callweaver, Asterisk

I am looking for a company with extensive knowledge to help us build our Hosted VoIP Platform.

We are looking for someone who is competent working with OpenSER or OpenSIPS, Has strong PERL Programing Skills, understands the Perl Integration Aspects with OpenSER and can provide ongoing support and maintenance.

The System should be multi-tenant, scalable and load balanced. It should have NAT Traversal

working. The System should Use Asterisk for a Media Server or an Alternative would be okay as well. Asterisk should act as a PSTN Gateway as Well as an IVR Server. We would also need to provide some sort of Faxing capabilities as well.

The dialing engine should handle multi-tenant scenarios and use AGI to offload the routing into module that uses a database which can be modified via a web-GUI.

We would also need an online web gui to provide basic management of the system and user provisioning as well as call routing.

I know a few tools out there that exist to make the task easier, and I am sure many developers have also built existing products for other vendors.

Our budget is realistic, and are looking at firms/people, who can provide ongoing support as well as part of the project scope.

Please post your experience with the described technologies as well as rate and what you can delever.
