Local ports for streams and SIP are not configurable

Submitted by Austin Lund Link to original bug (#619568)
Description
My ISP blocks UDP ports except in particular ranges (e.g. allows ports 50000-50050).
Currently it is not possible to specify these ranges to ensure that traffic of forwarded.
A work around for SIP is to update the local-port variable using mission control:
$ mc-tool update sofiasip/sip/account uint:local-port=50000
This ensures that SIP/SDP messages get through. However this still leaves the RTP streams blocked.
They appear to be hard-coded in telepathy-farsight to start at port 7078 for audio and 9078 for video. It would be nice to be able to configure this starting port or have some arrangement to ensure the ports are negotiated within the allowed range.
