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>
