If yes, just change your checks accordingly in order to make sure
to fetch a T38 INVITE/RE-INVITE.<br>

If you want to discard all INVITEs with T38, you can try to
add something like that in your
/etc/ngcp-config/templates/etc/kamailio/proxy/proxy.cfg.customtt.tt2:<br>
<br>
<br>
if(is_method("INVITE") && search_body("udptl"))<br>
{<br>
sl_send_reply("488", "Not Acceptable Here");<br>
exit;<br>
}<br>
<br>
before to send the invite to ROUTE_INVITE.<br>
Then run "ngcpcfg apply".<br>
<br>
So, each INVITE/REINVITE with udpl in their body will be
discarded.<br>

Basically on kamailio proxy you should match a Re-invite
(using the "has_totag") and check if SDP contains t38
headers/codec (just have a look how the T38 reinvite looks
like).<br>
So, if you receive a re-invite with T38 headers into SDP,
just send back a 488 reply.<br>

I think you need to avoid to forward the T38
Re-INVITE, so you should hack your SPCE in order to
reply to the T38 re-invite with a "488 Not acceptable
here", for example.<br>
So the sender SHOULD fallback to G711.<br>
Anyway, the best solution if you have endpoint with
t38 enabled but they don't work well, is to disable
t38.<br>
