Connecting 2 asterisk machines

ckleea

Would like to discuss on the best methods to connect 2 asterisk machines

Two methods exist
1. SIP
A machine is acted as sip provider and allows B machine to connect as sip client, vice versa.
It is similar to what one login to their own VOIP provider

E.g. in sip.conf
register = 3250:3250T03250@192.168.xxx.xxx/ast18
[sipast18]
disallow = all
allow = ulaw
allow = alaw
host = 192.168.xxx.xxx
fromdomain = 192.168.xxx.xxx
insecure = no
secret = 3250T03250
type = peer
username = 3250
context = from-ast18

in extensions.conf, I have the following for outbound

[CallingRule_ast18]
exten = _3XXX,1,Dial(SIP/sipast18/${EXTEN},,r)
exten = _3XXX,n,Hangup()

for inbound,
[from-ast18]
exten = ast18, Dial(SIP/6100,,r)

2. IAX - inter
The protocol provided by asterisk
my example is similar to what I set in the sip.conf. need also inbound and outbound setting in extensions.conf

further examples can be found here

Sometimes, IAX connection not working well.

How about your experience?

Both within the same LAN and over internet

For same LAN, has been no problem at all.
Over internet, it is a different issue. For me, I have test on SIP e.g. YH has been providing trunks for other users and I have done so as a provider before.
For IAX, it is an interesting option as it needs to have only one port open.

GUI is always a problem for us.
