[Asterisk-Users] Linking Asterisk Boxes with Sip

[Matt]

Not sure what's up with the mailing list here.   For some reason mails
are not coming through.

Try again...

I am trying to link an asterisk box to my provider's asterisk server
via SIP. (I know I could use IAX, but the provider does not allow
that, so I can't).  When an inbound call happens I get this:

Jan 31 13:09:14 NOTICE[3716] chan_sip.c: Failed to authenticate user
"+15703232166" <sip:+15703232166 at 63.174.244.172>;tag=as3e2d0c2d


The config looks like this:
[general]

port = 5060           ; Port to bind to (SIP is 5060)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
disallow=all
allow=ulaw
allow=alaw
context = from-sip-external ; Send unknown SIP callers to this context
callerid = Unknown
