[asterisk-users] Possibly I don't understand sip peers

[Bruce Ferrell]

I have a carrier who tells me he will be sending me traffic from a wide
range of IP addresses.

so I set up a realtime peer as follows:

[peer]
defaultip=xxx.xxx.xxx.xxx
host=xxx.xxx.xxx.xxx
deny=0.0.0.0/0.0.0.0
allow=xxx.xxx.xxx.0/255.255.255.0
insecure=port,invite


Yes, he's really claiming to originate from any of the IP in the block

When I leave the host blank, we reject calls with a 404.

shouldn't I be able to put in a kind of "wildcard" for his IP block or
am I just being silly?  If not, what am I doing wrong?
