= peering and trunking =



== links on asterisk peering ==

peer 2 asterisk boxes using IAX2 (easier for firewalling then SIP)
* http://etel.wiki.oreilly.com/wiki/index.php/Peering_two_Asterisk_servers_using_IAX
* the o'reilly book also has some info on peering and trunking, both using SIP and IAX2 (p111 in second edition)


== config we tried (later that night, by ptr_) == 

we have two asterisk boxes:
* idelix (on 172.22.33.23)
* obelix (on 172.22.33.75)

i only document the setup on idefix -- obelix is alike...

iax.conf -- each box sets up an account for iax2 peering

register => idefix:welcome@172.22.33.75

[obelix]
type=friend

</pre>


extentions.conf -- we added the [incoming_obelix] context (calls coming in/going out to our obelix-peer) and a dialplan with prefix extention number.
