Squillo.it - see http://www.squillo.it - is an Italian VoIP company offering geographical termination in SIP.

To connect your Asterisk box to Squillo, you should edit the following files:

– sip.conf –

[global]
....
canreinvite=no
register => **USER**:**PASS**@sip.squillo.it

[squillo]
type=friend
username=**USER**
fromuser=**USER**
secret=**PASS**
host=sip.squillo.it
context=from-squillo
insecure=very
disallow=all
allow=ilbc
allow=gsm
allow=ulaw
allow=alaw
dtmfmode=rfc2833

This way you register to Squillo as if your * box was a simple telephone. Incoming calls are routed to the context from-squillo.

– extensions.conf –

[default]
exten => _0.,1,Dial(SIP/${EXTEN:1}@squillo,30,tr)

[from-squillo]
exten => s,1,Dial(SIP/501,30,tr)

This example shows how to place and receive calls from Squillo (in this example, all incoming calls are routed to the single telephone SIP/501).
