My BT100 won't register with my Asterisk server, it always comes back with a 403. I've included my sip_additional (only one to to have the username 2201) and a portion of the sniffer trace (packets 27 & 28). This has me puzzled as I have my SPA-3K working (incoming and outgoing). On my BT100 I get no dial tone, I can't call it (asterisk says the extension is busy) but I can call out from my BT100 to other extensions and through the SPA to the POTS line. Don't assume I really know what I'm doing. One minute it all makes sense and the next I'm clueless. Thanks Oh, I trimmed the sniffer trace to only include the SIP decode. ============================================================================= [2201] username = 2201 authuser = 2201 secret = 2201 type = friend host = gs1.uucp ; host = 192.168.24.192 port = 5060 context = from-internal callerid = "Grandstream" <2201> mailbox = 2201 nat = never dtmfmode = rfc2833 canreinvite = yes qualify = yes ; qualify = no ; outgoinglimit = 2 ; permit only 1 outgoing call at a time ; incominglimit = 1 ; disable callwaiting signal (2nd call to phone) disallow = all ; need to disallow=all before we can use allow allow = ulaw ; Note: In user sections the order of codecs ; listed with allow= does NOT matter! allow = alaw =============================================================================No. Time Source Destination Protocol Info 27 453.810961 gs1.uucp mozart.uucp SIP Request: REGISTER sip:asterisk.uucp (remove all bindings) =============================================================================Session Initiation Protocol Request-Line: REGISTER sip:asterisk.uucp SIP/2.0 Method: REGISTER Resent Packet: False Message Header Via: SIP/2.0/UDP 192.168.24.192;branch=z9hG4bKd57bf9e7269cdaee From: "Neil J.
