I use freephoneline.ca as gateway and recently they have had several outage where either or both in and outgoing stop working Their recommendation is to configure an alternative sip server as apparently one will always be working. On the page below they explain how their box are configure but I can't work out how to transfer it to a freeswitch config http://support.freephoneline.ca/entries/23120323-VoIP-Unlock-Key-Credentials Is it possible? /Philippe
