Anyone ever setup a SIP Trunk to Twilio using an SBC? I've got it partially working as my inbound calls work perfectly. But my outbound calls fail. I'm seeing the following flows...
invite ->
<-100 giving a try
<-407 Proxy Auth
ACK->
Invite SDP->
<-100 giving a try
Invite->
<-100 giving a try
<-183 Session Progress
<- RTP
Invite SDP->
<-183 Session Progress
<-200 OK
<-200 OK
<-200 OK
Invite SDP ->
<-200 OK
<-200 OK
cancel->
cancel->
cancel->
The outbound call rings the far end. Once the call is answered there's no audio. Then once the far end hangs up Twilio attempts to send the call 2 more time - 2 phantom calls from the PBX. The SBC Incident viewer only shows "BYE Message out of dialog."
