Pairing of sessions and phones

[sparre]

The system needs to know which phone (address + protocol) the user is going to work from.

The plan is that the user interface (Bob) should get a one-time code from Alice, which the user dials on his/her phone. This is then registered by the PBX (FreeSWITCH), which forwards the information to Alice, which again forwards it to the user interface (Bob).

Needs:

• Protocol/interface to handle pairing - including resetting it - with the user interface. (#101)
• Configure FreeSWITCH to forward the one-time code to Alice. (FreeSWITCH-Configs#2)
• Implementing the protocol in Alice and Bob.

For now static mapping is acceptable.
