[Asterisk-Users] Hmmm - anyone seen this before?

[Steven P. Donegan]

The below is a asterisk message when I try to call from a callerid 
blocked phone into a SIP (Sipura 3000) FXO gateway - and I have not 
consciously put any restrictions on incoming calls...

Dec 29 10:23:44 NOTICE[2745]: chan_sip.c:7486 handle_request: Failed to
