Finally I got the GrandStream 486 talking through the Orange Livebox to the FaelixAsterisk VoIP exchanges in Manchester. In the end it involved setting the DMZ of the Livebox to point to the GrandStream. Now a Manchester-prefix number from SIPgate calls straight through into La Troïka! Calls from the Faelix office are, of course, free — it’s just an extension, after all!
