Hello,<br>
<br>
actually there is nothing wrong with the NOTIFY via TCP. But it is
not for Event: dialog (which is for BLF), it is for Event: refer
(which is for other purposes, having Content-Type: message/sipfrag
-- see <a class="moz-txt-link-freetext" href="https://www.ietf.org/rfc/rfc3420.txt">https://www.ietf.org/rfc/rfc3420.txt</a>).<br>
<br>
You have to see why freeswitch is not sending the notify for Event:
dialog. Does it send the 200ok for the SUBSCRIBE to event dialog?<br>
<br>
Cheers,<br>
Daniel<br>

<pre wrap="">Greetings all:
Having a weird issue with BLF relay from Kamailio <-> FreeSWITCH on the
EC2 network.
Set-up:
Natted Client <-> Natted Kamailio <-> Natted FreeSWITCH
Kamailio has a public advertised IP (Amazon Cloud) and sends to
FreeSWITCH's public IP (Amazon Cloud). Clients register to Kamailio and
the registration sent to FreeSWITCH (via uac).
What works:
When a client registers to kamailio via UDP, all works beautifully.
What doesn't work:
When a client registers to kamailio via TCP, a NOTIFY is sent with
almost no information.
Example of UDP traffic:

My thoughts is that this is on FreeSWITCH, just not sending a NOTIFY
with anything of value. That being said, I'd love to know if (a) anyone
else has had this issue or (b) if someone has a different theory.
Thanks!
