Re: [SR-Users] Keepalive dialog with SIP/TLS OPTIONS

Hello, this sounds strange. There is no TLS specific code in the dialog module. As a workaround, you could use for example SIP Session Timer for periodic re-INVITEs.

In order to keep the SIP/TCP connection alive for some specific clients (more precisely, specific firewalls) in long calls, I use periodic SIP OPTIONS probes through the dialog module. I noticed that when subscribers are using the SIP/TLS protocol, such keepalives are not sent (with SIP/UDP and SIP/TCP working well). I did not detect any obvious errors in the debug mode. Are there any ideas why the messages are not being sent for SIP/TLS leg? ---- loadmodule "dialog.so" modparam("dialog", "db_url", "DBURL") modparam("dialog", "db_mode", 1) modparam("dialog", "ka_timer", 5) modparam("dialog", "ka_interval", 30) modparam("dialog", "ka_failed_limit", 2) modparam("dialog", "send_bye", 1) modparam("dialog", "track_cseq_updates", 1) modparam("dialog", "default_timeout", 7205) ----- dlg_manage(); dlg_set_property("ka-src"); dlg_set_property("ka-dst"); -- BR, Denys Pozniak
