I was going to do that, except James K6JWN mentioned that there is no 
traffic on the link, unless I get an incoming call.  He suggested I 
try a dummy node using ztdummy and then using the method you used to 
bring in the link.  Haven't finalised my configs yet, so yet to fire 
up the node.  I may be doing the occasional outbound call once I can 
establish an Asterisk reflector out there (I don't have the CPU or 
bandwidth to support conferencing locally), but my remote sites can't 
run the meetme conference, because they can't load ztdummy (Virtuozzo  VPS).

Well, I will initially be linking remotely, the local IRLP node is 
not yet ready for linking to Asterisk, because the IRLP scripts don't 
integrate well.  I would have to upgrade it to my beta code to allow 
the local node to work.  That's getting higher up the todo list. :)

I will also need to know how to connect to other nodes as well. :)
