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. Leo
