Java Expert (+5 yrs)

I need to customize a Java open source sip auto dialer.

The person needs to be an expert with a clear knowledge about voip.

the opensource with the source is at GitHub: [login to view URL]

Basically, I want the software to perform a call hold, dial on the same port another call, then upon the success of that call, bridge that call with the call in hold.

The software will dial to an IVR and the purpose of this job is to be able to use the same port 6 of a maximum of 6 calls, that is allowed by the sim card into the gsm gateway.

so, we need to add that feature to open source.

If you feel you can do this job, please send me feedback to discuss price and timing, we need this asap, thanks!
