[Asterisk-Users] problem connecting to icallglobe

[Leo Ann Boon]

Anyone has successfully used Asterisk with icallglobe's SIP termination 
service? I'd been trying to get my Asterisk box to terminate 
international calls through them. Asterisk seems to register OK, but 
whenever I send a call to icallglobe's gateway, I always get a '403 
forbidden'.

What I've done so far:
a. register with their gw in sip.conf
b. Defined a peer [icallglobe] in sip.conf
c. Set secret, username, fromuser, fromdomain etc
d. In my extension.conf, I have
    exten => _0XXX.,1,Dial(SIP/${EXTEN}@icallglobe)
e. At the asterisk console, I used 'sip show registry' to make sure the 
status is 'registered'

When I make a call, * will send an INVITE to icallglobe's gateway but it 
always gets back a '403 Forbidden'. For example, if I dial '0651711' on 
my phone, I can see * dialing '651711@<icallglobe gw IP>'. After a 
while, * complains about getting '403...' from <icallglobe gw IP>.

Did I missed the obvious?

Cheers and TIA.
