[sr-dev] NOTIFY being sent through UDP instead of TCP

Hello list, I have some trouble with the presence module, I'm registering and subscribing to a presentity through TCP, and kamailio is sending me NOTIFY to the correct ip/port, but through UDP. I have checked in modules_k/presence/notify.c::1578, the value of the dialog's proto field is PROTO_TCP. but It's looke like that the function modules/tm/uac.c:t_uac_prepare() is trying to guess the transport (in ut.h at line 319 the function sip_hostport2su choose UDP as transport) instead of using the one present in the dialog. And as result I'm getting this warning and the NOTIFY through the wrong transport: 1(28921) WARNING: <core> [forward.c:248]: WARNING: get_send_socket: protocol/port mismatch It's maybe a foolishness from my part but why can't we just use the dialog's transport for the notify request, so it will be the same transport as subscribe ? In forward.c:242, when we find that force_send_socket->proto != guessed_proto, why we don't use the force_send_socket proto ? What do you think about it ? If someone want to take a closer look, I can post a sipp scenario which reproduce this issue. Thanks by advance, -- Nikita
