Asterisk replying to IAX packets, but nothing can be seen on console or in logs

Up until yesterday we had an IAX link which worked between two Asterisk systems.

No config was changed on either system, as far as anyone knows. Nor was either firewall changed.

tcpdump shows IAX packets arriving and being answered, when a call is attempted from the remote to my local asterisk box.

16:17:48.052552 IP (tos 0xb8, ttl 58, id 56200, offset 0, flags [none], proto UDP (17), length 152) > .4569: [udp sum ok] UDP, length 124
16:17:48.053657 IP (tos 0x0, ttl 64, id 37648, offset 0, flags [none], proto UDP (17), length 93) .4569 > [udp sum ok] UDP, length 65

(I know that the reply packets come from a different address, this was also the case when it was working.)

Running Asterisk in the foreground, with six v’s shows no evidence of the IAX packets at all.

How can I see what my local Asterisk thinks of these packets?
