Allow associating SIP account to specific network (alternative to network watch: libnm)
It would be nice if we could associate SIP accounts with specific networks, f.e. only ever try connecting to the SIP server of my ISP when at home, connect to SIP server foo when in VPN bar, etc...
For this we should use libnm.
We currently use the CallsNetworkWatch
to watch for changes in the default route and grab IP addresses of the interface used for the default route.
When the IP address changes it is used to trigger reconnecting SIP accounts (for those that are set to auto connect).
The same thing could also be done more robustly/reliably (see #414 ) with libnm.
