Okay, it turns out I was being stupid. ZapRAS does not automatically
answer the channel, so, the PRI_NET side below should have read:
PRI_NET side
--------------
extensions.conf:
[incoming]
exten => 6999,1,Answer
exten =>
6999,2,ZapRas(debug|64000|noauth|multilink|netmask|255.255.255.0|192.168.10.2:192.168.10.1)
I have added this as a note to the Wiki:
http://www.voip-info.org/tiki-index.php?page=Asterisk+cmd+ZapRAS
