KamailioProxy: Should kamailio do handshake or asterisk?
by Fernando Lopes 01 Jul '25

01 Jul '25

Hello everyone, I have Kamailio set up as a proxy between external clients and an Asterisk server. When traffic comes in over WSS, should Kamailio handle the TLS handshake, or should it be passed through to Asterisk? Thank you.

I encountered a problem when using dmq and dmq_usrloc. When I used the save function to save to the location table in the database, the socket field was sometimes empty, which caused problems with my call.

My dmq configuration： loadmodule "dmq_usrloc.so" modparam("dmq_usrloc", "enable", 1) modparam("dmq_usrloc", "sync", 1) modparam("dmq_usrloc", "usrloc_domain", "location_shuidi_online_agent") modparam("dmq_usrloc", "batch_size", 1000) modparam("dialog", "enable_dmq", 1) loadmodule "dmq.so" # ----- dmq params ----- modparam("dmq", "server_address", DMQ_SIP_URL) modparam("dmq", "server_socket", DMQ_UDP_URL) #!ifexp POD_NAME == "kamailio-cti-xyy-0" modparam("dmq", "notification_address", "sip:kamailio-cti-xyy-1.kamailio-cti-xyy-headless.devops.svc.bedin.bj3:5062") #!endif #!ifexp POD_NAME == "kamailio-cti-xyy-1" modparam("dmq", "notification_address", "sip:kamailio-cti-xyy-0.kamailio-cti-xyy-headless.devops.svc.bedin.bj3:5062") #!endif modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 15) Report an error： NATMANAGE cline: c=IN IP4 10.21.24.151 1(11) WARNING: <core> [core/msg_translator.c:2904]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found 1(11) ERROR: <core> [core/msg_translator.c:2044]: build_req_buf_from_sip_req(): could not create Via header 1(11) ERROR: tm [t_fwd.c:482]: prepare_new_uac(): could not build request 1(11) ERROR: tm [t_fwd.c:1759]: t_forward_nonack(): failure to add branches 1(11) ERROR: sl [sl_funcs.c:415]: sl_reply_error(): stateless error reply used: Message processing error (2/SL) I think the reason is that the socket field in the location database is copied to another kamailio node and then updated to the database, causing it to be overwritten and empty. A part of location database table： user_agent socket methods SIP.js/0.21.2 5023 SIP.js/0.21.1 5023 SIP.js/0.21.2 5023 SIP.js/0.21.1 5023 SIP.js/0.21.2 5023 please help ！！！ I really don't know how to prevent the socket field from being overwritten.
