OpenSER (Kamailio) + Asterisk + A2Billing platform

I have an a2billing + asterisk working in realtime. But i have issues with nat clients so i'm thinking to use Openser to solve nat issues and also get a more scalable system. I will give you Teamviewer access. So i need the following:

We need a serious professional to install and configure an OpenSER (Kamailio) integration with our Asterisk + A2Billing platform.

- OpenSER should act as Registrar with Nathelper + RTPProxy/MediaProxy and it should allow local users to call each other without passing through Asterisk. It should also route local, national and international calls like (011/00 prefix) to Asterisk + A2Billing. OpenSER should use a View of the A2Billing database to authenticate users.

- Asterisk + A2Billing should be configured so that new user accounts would be created in A2Billing. Also, each user should have their own voicemail account and OpenSER should route unanswered/failed calls to the user's voicemail.

- Wholesale inbound calls should be authenticated by IP address.

Server 1 = It Has Asterisk realtime + A2billing (i got now configured)

Server 2 = It Has Database (i got now configured)

Server 3 = it Must have openser (not configured)


voip clientes ----->Openser---->asterisk+a2billing

Since asterisk + a2billing are configuring and working, you wll only need to work with openser integration.

We need also support for openser in the future so this it will be a long term project.

If you have experience with openser + asterisk + integration don't doubt to bid... If not.. please don't loose your time.


Budget is not more than $300 for this Job, i have seen all similar integrations here like:


Also i have all installed asterisk, a2billing etc. i only need SER with integration.

so.. pelase fix your bid closer to budget and lets go to start.
