[SR-Users] Problem implementing Outbound Proxy

[Christoph Russow]

yeah the only thing different are the private ips and the record-route 
headers.

the carrier needs a special request thats why the +e164 to and e164 
everywhere else and the <prefix>e164 in invite header.

if i start the call directly from freeswitch to the carrier (without 
kamailio proxy) it works.

so i think maybe (as this is our main carrier) i need some other way to 
solve that.

Best regards
Christoph
