<h3 dir="auto">Description</h3>
<p dir="auto">When dialog module needs to send keep-alive to caller and/or called it doens't check if the ip address and port of the dialog is the current listening ip/port. If you have two distinct kamailio instances sharing a single dialog database, both instances are sending the OPTIONS and not just the one which handled the call at setup time.</p>

<h3 dir="auto">Troubleshooting</h3>
<h4 dir="auto">Reproduction</h4>
<p dir="auto">Start two instance with a shared dialog database and db_mode set to 1 (realtime), set property ka-src for every dialog in kamailio cfg. Setup a long call and restart the instance not involved in the call. You should see it starting to send OPTIONS.</p>
<h3 dir="auto">Possible Solutions</h3>
<p dir="auto">In dlg_send_ka, if the ip/port stored in the dialog db is not present in the listening ip/port set, skip the check.</p>
