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

Hi Christoph,
sorry i overlooked that. Seems okay to me. So IMHO its "okay" in SIP.
Your Carrier didnt like it.
First - i would try to ask the Carrier -
The Error Message "503 Service Unavailable-No Bandwidth Available" seems
to me like a blocking rule on the carrier side.
Could be mixed +e164 (in To) vs e164 in From/PAI/whatever - the
Contact-Header or something else.
The other way is to capture a working outbound call and then try to
check what's different.
Best

hi,
thats what i did on our application servers (freeswitch gateway
config).
kamailio routes the calls as wanted but the carrier rejects it (see
pcap
file in first email).
