SFLPhone Fails to start - solved

Sometimes SFLPhone (a VOIP client) will completly fail to start and give a generic useless error about "Make sure the daemon is running" which doesn't help because you will find it is not running and you cant start it either.

The solution?

simply do the following command:

rm ~/.cache/sflphone/sfl.pid

That will remove the lock file, sflphone clietn will start up and start the deamon as well.
