mgcp: FreeSWITCH requiresn us to provide the o= and t= param
The SDP file for FreeSWITCH should contain o= (Origin) and the t= (Timing) for the session. The data of the Origin should be globally unique but this is not the case yet. We will need to store the (NTP) time of the creation of the endpoint.
