Has anyone sucessfully placed a call to a vonage user using one of the sip peering networks. I am trying to use sipbroker and use exten => <number>,1,Dial(Sip/*472<number>@sipbroker.com) i have even tried calling: <number>@sphone.vopr.vonage.net I get the same return message from sipbroker as i do with sphone.vopr.vonage.net. "circuit is busy".. does this mean that sipbroker is working? or just that vonage just isn't taking any calls in on their server? ..??? Thanks.
