Hi, we are currently using an Elastix ELX3000, from the original country...Ecuador..jejeje..well we have setup a Vonage trunk with this info: Vonage auth=md5 context=from-pstn dtmfmode=inband fromdomain=216.115.20.41 fromuser=XXXXX(number) hidecallerid=yes host=216.115.20.41 nat=yes port=5061&5060 secret=XXX(PASSWORD) type=peer qualify=yes insecure=port,invite Vonage-in auth=md5 canreinvite=no context=from-pstn dtmfmode=inband fromdomain=216.115.20.41 fromuser=XXXXX(number) host=216.115.20.41 insecure=port,invite nat=yes port=5060&5061 secret=XXX(PASSWORD) type=friend username=17863755167 qualify=yes and the register string: XXXXX(number):XXX(PASSWORD)@216.115.20.41 Well, the incoming when the people call to my XXXXX(number) everything is great...the IVR popups and everything is cool, the problem is for the outgoing we have an outbound route for the vonage(866) when we dial 8667860000000 where 7860000000 is any number in USA, the elastix says..."todas las lineas estan ocupadas" is because is in Spanish...in Enlgish would be "all circuits are busy now" when i ssh asterisk -rv sip set debug peer vonage the message is: <--- SIP read from UDP:216.115.20.41:5060 ---> SIP/2.0 407 Proxy Authentication Required Via: SIP/2.0/UDP 216.115.20.41:5060;branch=z9hG4bK15246302;rport From: "Unknown" <sip:Unknown@190.95.215.147>;tag=as309ea2ac To: <sip:216.115.20.41>;tag=88505388 Call-ID: 0d9b99073eee7ce201a817a56f5a49e9@190.95.215.147 CSeq: 102 OPTIONS Proxy-Authenticate: Digest realm="216.115.20.41", domain="216.115.20.41", nonce="509222372", algorithm=MD5 Max-forwards: 70 Content-Length: 0 <-------------> Any help would be great Regards Marco Paucar
