Hi, i have mwi running on a server and everything works as expected but notifications over TLS are not sent. i tried this with several ip phones (hard and soft) i can register over tls, make calls, etc the initial SUBSCRIBE sent by client works as expected and answer is sent and received. when the NOTIFY is initiated by the server here is what i get. i setup some extra debug settings any thoughts ? thank you Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1681]: notify(): updating subscription to database Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:117]: printf_subs(): pres_uri: sip:995582130@teste.sip.90e9.com Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:121]: printf_subs(): callid/from_tag/to_tag: 73da11de-3566eef2(a)192.168.16.15/b302146219721c3/804318313668236640636a8c49438852-3fce Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:122]: printf_subs(): local_cseq/remote_cseq: 7/1005 Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:123]: printf_subs(): local_contact/contact: sip:192.168.16.145:5061 ;transport=tls/sip:995582130@192.168.16.15:5074;transport=tls Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:124]: printf_subs(): record_route: Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:125]: printf_subs(): sockinfo_str: tls:192.168.16.145:5061 Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:127]: printf_subs(): event: message-summary Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1591]: send_notify_request(): expires 172 status 1 Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1603]: send_notify_request(): STEP 1 Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1606]: send_notify_request(): STEP 2 *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: : <core> [pass_fd.c:157]: send_all(): ERROR: send_all: send on 17 failed: Bad file descriptor* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: ERROR: <core> [tcp_main.c:2353]: tcpconn_send_put(): BUG: tcp_send: failed to get fd(write):Bad file descriptor (9)* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: ERROR: tm [../../forward.h:237]: msg_send(): msg_send: ERROR: tcp_send failed* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: ERROR: tm [uac.c:506]: send_prepared_request_impl(): t_uac: Attempt to send to precreated request failed* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1608]: send_notify_request(): STEP 3* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:1621]: send_notify_request(): NOTIFY sip:995582130@teste.sip.90e9.com via sip:995582130@192.168.16.15:5074;transport=tls on behalf of sip:995582130@teste.sip.90e9.com for event message-summary* *Aug 31 23:46:42 sipproxy-01 kamailio[3041]: INFO: presence [notify.c:3107]: pres_notify_watchers(): step 13* -- Luis Azedo
