[Asterisk-Users] Busy signal for incoming calls from broadvoice

[Robert La Ferla]

When someone calls me via BroadVoice, they get a busy signal.  My * box 
is behind a NAT firewall.  I have enabled port forwarding of UDP 5060 
and 10000:20000 to the * box.  I added nat=yes  externalip and localnet 
to the sip.conf under [general].  It still doesn't work.  I just want * 
to be able to answer the phone and send the caller to voicemail 
directly.  What could be the problem?
