[Asterisk-Users] Issue with trunking

[Tom Storey]

Hi all.

Ive recently setup two Asterisk boxes (running Asterisk at Home to be specific), and Im trying to get a trunk going between them.

So far I have tried a combination of IAX and SIP configuring them through AMP and writing the config files manually, but I cant seem to get calls going between the two.

I have named each box asterisk1 and asterisk2.

Does anyone have some working SIP and/or IAX trunk configurations they can send to me?

Here is my current SIP config which doesnt seem to work:

sip.conf on asterisk1:

register=ast1:****@x.x.x.x

[100]
username=100
type=friend
secret=****
record_out=Never
record_in=Never
qualify=no
port=5060
host=dynamic
dtmfmode=rfc2833
context=from-internal
canreinvite=no
callerid="Ext 100" <100>

[ast2]
type=user
secret=****
context=local

[astrx2]
username=ast1
type=peer
secret=****
host=x.x.x.x


sip.conf on asterisk2:

register=ast2:****@y.y.y.y

[101]
username=101
type=friend
secret=****
record_out=Never
record_in=Never
qualify=no
port=5060
nat=never
host=dynamic
dtmfmode=rfc2833
context=from-internal
canreinvite=no
callerid="Ext 101" <101>

[ast1]
type=user
secret=****
context=local

[astrx1]
username=ast2
type=peer
secret=****
host=y.y.y.y


Where x.x.x.x and y.y.y.y are the IP addresses of each opposite box respectively (I'd put the real IPs in there but they are public routable ones  :-) )

Basically what I get is the following:

If I dial 43100 from ext 101 on asterisk2, this should transfer the call to asterisk1 and ring ext 100 on asterisk1. All I get is "all circuits are busy".

If I dial 44101 from ext 100 on asterisk 1, it should send the call to asterisk2, but I get absolutely nothing. Not an error tone or even a ringing sound.

When I look at Asterisk Info via AMP this is what I see under SIP peers:

on asterisk1:
x.x.x.x:5060               ast1               120 Request Sent        

on asterisk2:
y.y.y.y:5060               ast2               120 Unregistered        

Does anyone have any ideas as to why or what might be happening and how I can fix it?

Cheers,
Tom
