If the prilocaldialplan is set to 'unknown' or 'dynamic', then you send the '1'. If the prilocaldialplan is set to 'domestic', then you leave the '1' off (because it's implied). In terms of SIP or another VoIP protocol, you use whatever your provider specifies. -- Tilghman Lesher Digium, Inc. | Senior Software Developer twitter: Corydon76 | IRC: Corydon76-dig (Freenode) Check us out at: www.digium.com & www.asterisk.org
