I think he’s trying to reply to the client immediately with a 200 and
consume and not forward the 200 coming from the presence servers.

If you need to stop the retransmission, a 100
trying should be sent
instead of 200ok. Can you reconfigure the next hop to do
that? Or is it out
of your control?
Looks it is difficult to do this as Kamailio Proxy forks via
append_branch() incoming SIP PUBLISH to all Presence Servers.
I do not understand what is difficult, to configure the next hop
application to send 100 trying? Or maybe you can provide a diagram of how
sip traffic is routed on your case.
And even if Presence Server answers 200 OK, the Kamailio Proxy still sends
a repeated SIP PUBLISH there within the fr timer.
This remark is also not clear, is the 200ok handled by Kamailio, sent
upstream, but then Kamailio still resends the PUBLISH?
Cheers,
Daniel

Hello,
if the 200ok is consumed by tm, it will destroy the transaction very
soon. I am not sure this is a good path to go.

Hello!
In the configuration below Kamailio Proxy creates a transaction for the
SIP PUBLISH to get info from the HTTP server in async mode.
But before creating a transaction, a synthetic 200 OK is sent, so that I
need somehow to drop the real 200 OK from the upstream Presence Server.
If drop 200 OK in *reply_route*, tm module starts to retransmit.
Those it is necessary that the 200 OK be consumed by the tm module, but
does not go further.
*if ( !is_method("PUBLISH") ) { *
* sl_send_reply("200", "Ok"); t_newtran(); *
* $http_req(suspend) = 1; http_async_query("$var(url)",
"CALLBACK"); *
*}*
*route[CALLBACK] { *
* <some header manipulation>*
* t_on_reply("PUBLISH_REPLY"); route(RELAY); exit;
*
*}*
*onreply_route[PUBLISH_REPLY] { if ( t_check_status("200") ) {
drop; # Does not work!!! } } *
Any advice is appreciated
